Changelog: [Internal]
The crash is caused by dereferencing invalid pointer.
This can happen because `UIManager` can outlive `RCTScheduler` and `Scheduler`.
Here we make sure when `Scheduler` is being deconstructed, UIManager's pointer is invalidated.
I don't think this is ideal solution but it should fix the crash.
Ideally we want the owner of animation delegate to invalidate the pointer.

Summary:
This diff disables the state list animator from the ReactSlider object used to measure ReactSlider.
The motivation is to fix T63030542, which it seems to be caused by the state list animator being accessed and modified from different threads
We don't have a way to reproduce, but based on my analysis this diff will fix T63030542.
I would like to land this diff and then keep tracking production data for the crash reported on T63030542

As a simple refactor, I want to 1) have `synchronouslyUpdateViewOnUIThread` only catch exceptions for the specific MountItem being synchronously executed, 2) not assume that scheduleMountItem will always cause synchronous execution.
I think this makes the logic here a little more clear and it scopes how we swallow exceptions, which could be swallowing too many errors right now actually.

Summary:
There are two ways to make a NativeModule method execute synchronously:
- Declare the NativeModule method to be synchronous (i.e: use `RCT_EXPORT_BLOCKING_SYNCHRONOUS_METHOD`).
- Make the NativeModule synchronous (i.e: make its method queue `RCTJSThread`). This way, all its methods are synchronous.
`RCTNativeModule` executes all synchronous methods on the JS thread:
- Executing an async methods on a sync module: https://git.io/JfRPj
- Executing a sync method: https://git.io/JfRXe
However, in TurboModules we block the JS thread, execute the method on the NativeModule's method queue, and then unblock the JS thread. While this approach is thread-safe, and arguably the correct way to dispatch sync methods, it's also much slower than the alternative. Therefore, this diff migrates the legacy behaviour to the TurboModule system.
## Special Case: getConstants()
When an ObjC NativeModule requires main queue setup, and it exports constants, we execute its `constantsToExport` method on the main queue (see: [RCTModuleData gatherConstants](https://github.com/facebook/react-native/blob/c8d678abcf93fd3f6daf4bebfdf25937995c1fdf/React/Base/RCTModuleData.mm#L392-L402)). I replicated this behaviour with TurboModules.

Summary:
## Context
- If a NativeModule requires main queue setup, its `constantsToExport` method is executed on the main queue.
- In the TurboModule system, `constantsToExport` or `getConstants` is treated like a regular synchronous NativeModule method. Therefore, it's always executed on the JS thread.
This difference in behaviour is dangerous when we're A/B testing the TurboModule infra: One could write a NativeModule that requires main queue setup, and have it expose constants that access objects/state only accessible on the UI thread. This NativeModule would work fine in the legacy infra, which could be the case if the NativeModule author is testing locally. But once it ships to prod, it may run with the TurboModule system, and crash the application. To mitigate this risk, I'm removing this special main queue execution of `constantsToExport` from the legacy infrastructure.
## Consequences
- If a NativeModule's `constantsToExport` method accesses objects/state only accessible on the UI thread, it must do so by explicitly scheduling work on the main thread. I wrote up a codemod to fix this for our OSS modules: D21797048.
- Eagerly initialized NativeModules that required main queue setup had their constants calculated eagerly. After the changes in this diff, those NativeModules will have their constants calculated lazily. I don't think this is a big deal because only a handful of NativeModules are eagerly initialized, and eagerly initialized NativeModules are going away anyway.

Summary:
If a NativeModule requires main queue setup, its `getConstants()` method must be executed on the main thead. The legacy NativeModule infra takes care of this for us. With TurboModules, however, all synchronous methods, including `getConstants()`, execute on the JS thread. Therefore, if a TurboModule requires main queue setup, and exports constants, we must execute its `getConstants()` method body on the main queue explicitly.
**Notes:**
- The changes in this diff should be a noop when TurboModules is off, because `RCTUnsafeExecuteOnMainQueueSync` synchronously execute its block on the current thread if the current thread is the main thread.
- If a NativeModule doens't have the `requiresMainQueueSetup` method, but has the `constantsToExport` method, both NativeModules and TurboModules assume that it requires main queue setup.

Summary:
`getStackTracesTreeNodeForAlloc` only works for memory that was tracked with `newAlloc`.
For now, that is only memory that goes through GC APIs.
Various places were calling this function on native memory which was allocated
with `malloc`, not GC memory. This led to SIGSEGV on nullptr when trying to take heap profiles
of these objects.
`newAlloc` could, in theory, work with native memory as well. But building out support for that
is outside the scope of this fix.

This strategy swizzles UIApplication handleKeyUIEvent which is further upstream than our UIResponder. It also allows for single key hotkeys like pressing just `r` instead of `cmd+r`. It does this without interfering with typing input by checking the first responder first.
I've also updated our hotkey handling to support using just the keys like `r` in addition to `cmd+r`. In addition to brining these hotkeys more in line with other iOS tools, they're also easier to use and do not suffer the same issues hotkeys with modifiers like `cmd` have where keys are dropped.

As a followup to D21750097 and D21735940, it seems that ANY uses of childCount will be incorrect as they are "often" reported, incorrectly, as just 0.
This is likely due to exotic cases like (1) the ViewManager childCount being overridden, or (2) special ViewManagers like BottomSheet where the childCount may actually be 1/0 even though many children are inserted.
Anyway, as a more generic fix, let's only rethrow an existing Exception with additional diagnostics instead of trying to detect when this /would/ crash.
