This moves the build of RNTester from Unix Make to CMake
This will serve as a blueprint for users that are looking into using CMake end-to-end in their buildls.
In order to make this possible I had to:
* Add an `Android-prebuilt.cmake` file that works similar to the `Android-prebuilt.mk` for feeding prebuilt .so files to the consumer build.
* Update the codegen to use `JSI_EXPORT` on several objects/classes as CMake has stricter visibility rules than Make
* Update the sample native module in `nativemodule/samples/platform/android/` to use CMake instead of Make

Summary:
The current implementation of `throwJSError` places it in jsi.cpp, but
does not actually export it. This means that when JSI is being provided
by a dynamic library, `detail::throwJSError` will not be available.
To fix this, move the definition of `throwJSError` into jsi-inl.h,
similar to all of the other functions in the `detail` namespace. This
uses a roundabout implementation of `throwJSError` in order to avoid
directly using `throw`, which would fail to compile when exceptions are
turned off.

Summary:
See also D36889794. This is a very similar idea, except the core problem is that BaseTextProps is accessing the same props as ViewProps; and for ParagraphProps parsing, it first defers to ViewProps' parser and then BaseTextProps. RawPropsParser is optimized to access the same props in the same order, *exactly once*, so if we access a prop out-of-order, or for a second time, that access and the next access are deoptimized. Paragraph/Text, in particular, were quite bad because we did this several times, and each out-of-order access requires scanning /all/ props.
This fixes the issue, at least partially, by (1) pulling all the duplicate accesses to the beginning of BaseTextProps, and (2) accessing them all in the same order as ViewProps, relatively (some props are skipped, but that matters less).
Practically what this means is that now, all of Props' accesses have a cost of O(1) for lookup, or a total of O(n) for all of them; each access is at the n+1 position in the internal RawPropsParser array, so each access is cheap. BaseTextProps' duplicate accesses, even though there are only 4 of them: (1) the first one scans the entire array until we reach the prop in question; (2) the next accesses require scans, but not whole-array scans, since they're in order. (3) The BaseTextProps accesses /after/ the duplicate accesses are all O(1).
tl;dr is that before we had something like O(n*6) cost for BaseTextProps parsing and now it is O(n*2).
Similar to my summary in the last diff: we may want to revisit the RawPropsParser API... but I want to tread gently there, and this gets us a large improvement without major, risky changes.
Empirically, based on a couple of systraces, average time for a single UIManager::createNode called from JS thread, before this stack: 17us. After: 667ns (3% as long). On average, for every 60 createNode calls, we will save 1ms on the UI thread. The savings will be greater for certain screens that use many Views or Text nodes, and lesser for screens that use fewer of these components.

Summary:
Without getting into the weeds too much, RawPropParser "requires" that props be accessed in the same order every time a Props struct is parsed in order to most optimally fetch the values in a linear-ish fashion, basically ensuring that each rawProps.at() call is an O(1) operation, and overall getting all props for a particular component is O(n) in the number of props for a given struct. If props are called out of order, this breaks and worst-case we can end up with an O(n^2) operation.
Unfortunately, calling .at(x) twice with the same prop name triggers the deoptimized behavior. So as much as possible, always fetch exactly once and in the same order every time. In this case, we move initialization of two fields into the constructor body so that we can call .at() a single time instead of twice.
In the debug props of ViewProps I'm also reordering the fields to fetch them in the same order the constructor fetches them in, which will make this (debug-only) method slightly faster.
What's the impact of this? If you dig into the Tracery samples, the average/median RawPropsParser::at takes 1us or less. However, in /every single/ call to createNode for View components, there is at least one RawPropsParser::at call that takes 250+us. This was a huge red flag when analyzing traces, after which it was trivial (for View) to find the offending out-of-order calls. Since this is happening for every View and every type of component that derives from View, that's 1ms lost per every 4 View-type ShadowNodes created by ReactJS. After just 100 views created, that's 25ms. Etc.
There are other out-of-order calls lurking in the codebase that can be addressed separately. Impact scales with the size of the screen, the number of Views they render, etc.

Summary:
This PR updates `RCTMountingTransactionObserving` protocol to accept full `MountingTransaction` object as an argument to its methods as opposed to just `MountingTransactionMetdata` which contained only some subset of information.
This change makes it possible for components implementing the protocol to analyze the list of mutations and hence only take action when certain mutations are about to happen.
One of the use cases for `RCTMountingTransactionObserving` protocol is to allow for Modal to take view snapshot before it is closed, such that an animated close transition can be performed over the snapshotted content. Note that when modal is removed from the view hierarchy its children are gone too and therefore the snapshot mechanism makes it possible for children to still be visible while the animated closing transition is ongoing. A similar use-case to that can be seen in react-native-screens library, where we use the same snapshot mechanism for views that are removed from navigation stack.
Before this change, we'd use `mountingTransactionDidMountWithMetadata` to take a snapshot. However, making a snapshot of relatively complex view hierarchy can be expensive, and we'd like to make sure that we only perform a snapshot when the given modal is about to be removed. Because the mentioned method does not provide an information about what changes are going to be performed in a given transaction, we'd make the snapshot for every single view transaction that happens while the modal is mounted.
In this PR we're updating `RCTMountingTransactionObserving` protocol's methods, in particular, we rename methods to no longer contain "Metadata" in them and to accept `MountingTransaction` as the only argument instead of `MountingTransactionMetadata` object. With this change we are also deleting `MountingTransactionMetadata` altogether as it has no uses outside the protocol. Finally, we update the two uses of the protocol in `RCTScrollViewComponentView` and `RCTModalHostViewComponentView`.
## Changelog
[iOS][Fabric] - Update RCTMountingTransactionObserving protocol to consume MountingTransaction objects
Pull Request resolved: https://github.com/facebook/react-native/pull/33510
Test Plan:
As there are not that many uses of `RCTMountingTransactionObserving` protocol during testing I focused on checking if the updated method is called and if the provided objects contains the proper data. Unfortunately, despite code for the modal protocol being present in OSS version it does seem like some parts of modal implementation are still missing and the component only renders an unimplemented view (checked this with rn-tester). I only managed to verify the use in `RCTScrollViewComponentView` with the following steps:
1. Build for iOS
2. Put a breakpoint in mountingTransactionDidMount method in `RCTScrollViewComponentView.mm`
3. Verify that the program stops on the breakpoint when a scrollview is rendered (use any screen on rn-tester app)
4. Inspect the provided object in the debugger (ensure the list of transactions is not empty)
Outside of that we verified the transactions can be processed in `mountingTransactionDidMount` after the changes from this PR are applied in FabricExample app in [react-native-screens](https://github.com/software-mansion/react-native-screens/tree/main/FabricExample) repo.

Summary:
Creates a `WritableMapBuffer` abstraction to pass data from JVM to C++, similarly to `ReadableMapBuffer`. This part also defines a Kotlin interface for both `Readable/WritableMapBuffer` to allow to use them interchangeably on Java side.
`WritableMapBuffer` is using Android's `SparseArray` which has almost identical structure to `MapBuffer`, with `log(N)` random access and instant sequential access.
To avoid paying the cost of JNI transfer, the data is only transferred when requested by native `JWritableMapBuffer::getMapBuffer`. `WritableMapBuffer` also owns it data, meaning it cannot be "consumed" as `WritableNativeMap`, with C++ usually receiving copy of the data on conversion. This allows to use `WritableMapBuffer` as JVM-only implementation of `MapBuffer` interface as well, e.g. for testing (although Robolectric will still be required due to `SparseArray` used as storage)

Summary:
This PR fixes RTTI (run-time type information) for ShadowNodeWrapper and ShadowNodeListWrapper classes, i.e., calls to dynamic_cast and dynamic_pointer_cast that are called via JSI's getHostObject calls.
The fix is simply to add a so-called "key function" in a form of virtual destructor. Key functions needs to be a virtual non-pure and non-inlined functions that points the compiler as to which library contains the vtable/type information for a given class (see https://itanium-cxx-abi.github.io/cxx-abi/abi.html#vague-vtable and https://developer.android.com/ndk/guides/common-problems#rttiexceptions_not_working_across_library_boundaries)
Without the "key function", calls to dynamic_cast for ShadowNodeWrapper instances won't work across library boundaries because the class will have separate definitions in each separate library, therefore objects created in one of those libraries won't be recognized as the same type by the other library. This has been a problem in reanimated and gesture-handler libraries where we call `object.getHostObject<ShadowNodeWrapper>(rt)` (this is a method from JSI) in order to access ShadowNode instance from a handle we have in JS. I think, this issue is going to be relevant to more libraries that cope with view instances. In this scenario, we have a separate library, say "libreanimated.so" that calls to `getHostObject` which is an inline function that calls `dynamic_cast` for the `ShadowNodeWrapper` class. On the other hand, the instances of `ShadowNodeWrapper` are created by the code from `libreact_render_uimanager.so`. Because of that `dynamic_cast` fails even though it is called on instance of `ShadowNodeWrapper` because the class has separate vtable/type info: one in `libreanimated.so` and one in `libreact_render_uimanager.so` (by "fails" I mean that it actually returns `nullptr`).
This problem has been documented here: https://developer.android.com/ndk/guides/common-problems#rttiexceptions_not_working_across_library_boundaries where the solution is for the class to have a so-called "key function". The key function makes it so that compiler sees that one of the implementation for a given class is missing and therefore can safely assume that a vtable/type info for a given class is embedded into some library we link to.
This change adds a virtual destructor that is declared in the header file but defined in file that gets compiled as a part of `libreact_render_uimanager`. As a result, the compiler only creates one vtable/type info and calls to dynamic_cast works as expected in all libraries for `ShadowNodeWrapper` and `ShadowNodeListWrapper` classes.
This issue would only surface on Android, because on iOS all libraries by default are bundled together via Pods, whereas on Android each library is loaded separately using dynamic loading.
## Changelog

2. After compiling the app inspect libreact_render_uimanager.so and libreanimated.so artifacts with `nm` tool
3. Notice that symbols like `vtable for facebook::react::ShadowNodeWrapper` and `typeinfo for facebook::react::ShadowNodeWrapper` are only present in the former and not in the latter library (before this change you'd see them both)
