Summary:
There can be a race condition between bridge invalidation (hence TM binding invalidation) with pending Promise reject/resolve invocation. If invalidation happens first, invoking the resolve/reject from ObjC class might end up accessing destroyed PromiseWrapper, causing hard crash randomly.
The proper fix is to switch the objc promise resolve/reject block (objc block) to use C++ PromiseWrapper directly, such that the lifecycle of the shared_ptr<> can be correct.

Summary:
This diff reimplements the prop parsing infrastructure in a part where it interacts with RawProps value.
Local synthetic tests show that the new way is 3x faster but the actual production result is quite unpredictable. MobileLab tests show some improvements about 10-20 ms on iPhone 6.
In short, the new way is faster because it inverts the lookup order and heavily relies on actual data types (and their properties) that we use. The old approach required about 130 hash-map lookups (where the key is `std::string`) to parse a single *Props object.
The new approach prepares concrete-props-specific tables with indexes of coming values ahead of time, iterates over raw data and puts it into those tables, and then performs a lookup in a very efficient manner.

Summary:
Previously we used `std::string` as a type behind all prop names (and name fragments). Even if `std::string` converted from `char const *` should be heavily optimized by STL and compiler, we still concatenate and copy those strings a lot. Switching to `char const *` allows avoiding tons of copying and inefficient equality checks.
Besides that, the future, more sophisticated optimization will rely on this.

Summary:
Address Sanitizer told me that I have UB in `RCTUIFontWeightFromFloat` and it was right. After a short investigation, I find out that the original assumption that `UIFontWeight` values are practically numbers from 100 to 900 was incorrect. In my simulator, it's something like from `-1` to `+1` (irregularly!). So, the whole subsystem worked only by accident.
This diff fixes that; now we never assume which actual values `UIFontWeight` constants have.
I will publish code style fixes as a separate diff (otherwise it will be really hard to review).

... and slighly new behaviour for one of them.
The method does nothing if given `key` already exists in the container.
This diff finishes the transition of ContextContainer from an internal bag of things with unclear yet ownership into a legit dedicated dependency injection container for the product code.
The original names of methods imply that the container can have only one object of a given type which is no longer true. The new API is much more generic and idiomatic to C++, it mimics `std:map` API which is intuitive to anyone who familiar with C++ containers.
Besides the naming, `insert` method changed the semantic a bit; now it does nothing in case of inserting an object with a key that already exists. That might seem counterintuitive for "normal" people, but C++ has some wired reasons for that and, hopefully, it's expected behavior in the C++ community.
Fun fact: We need this to fix hot-reload.

In addition, Rust considers `/**` to be a doc comment (similar to Javadoc) and having such a comment at the beginning of the file causes `rustc` to barf.
Note that some JavaScript tooling requires `/**`. This is OK since JavaScript files were not covered by the linter in the first place, but it would be good to have that tooling fixed too.

Summary:
First of all, seems it's the right thing to do. Fabric C++ code is cross-platfrom and should run on *all* platforms including Windows, Linux, and Mac.
While we don't have a real *production* use cases where we need compilation for desktops, having CXX target is really handy for two reasons:
* It simplifies local test running process. Instead of going to `/fbandroid/` and executing something like `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:coreAndroid` (note the suffix). We can just do `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:core` everywhere and it works now out of the box. Running tests with "Apple" flavor never worked for me.
* It allows creating synthetic benchmark tests (using Google Benchmark) that can be used as a rough approximation of code micro-optimizations.

If that global variable exists, we can use that to start the surface instead of calling AppRegistry.

```
After investigation we found that when using any bundle, let it be non-ram, FIle RAM bundle or Index RAM bundle, the `CatalystInstanceImpl.java` is always using `loadScriptsFromAsset`, which is calling `CatalystInstanceImpl::jniLoadScriptFromAssets` in C++. This method when checking if bundle is a RAM bundle, uses `JniJSModulesUnbundle::isUnbundle` which only check for js-modules/UNBUNDLE - file generated when building File RAM bundle. There is no other logic to handle Indexed RAM bundle, so it figures that the bundle is not RAM, cause there is no js-modules/UNBUNDLE file and tries to load as regular bundle and fails.
In this PR we added check if it is indexed RAM bundle in `jniLoadScriptFromAssets` and handle it if it is.

Replace the *copy on write* vector with an atomic pointer to a linked list.
This allows to publish without locking a mutex, at the cost of the slower traversal of a linked list (a vector has better locality).
At the moment, the typical use case is to have one subscriber, meaning that the afforementioned slower traversal is not a problem.
Adding subscribers is implemented as atomic *compare and swap.*

This diff does a few different things:
1. Unify iOS and Android by removing the `#ifndef` for Android so that we call `startSurface` for both
2. Pass through the JS module name on Android so that this actually works (it currently passes in an empty string)
3. Remove the call to `ReactRootView.runApplication` for Fabric so that we don't end up doing this twice
4. Copy over some logic that we need from `ReactRootView.runApplication` (make sure that root layout specs get updated, and that content appeared gets logged)
