Summary:
We currently use `BatchedBridge.registerCallableModule` to call JS from platform code in a bunch of places (e.g. `RCTDeviceEventEmitter.emit()`), including some pretty essential ones - for example, Networking relies on `RCTDeviceEventEmitter` to emit events to JS for network requests and errors. In order to make the migration to bridgeless mode as easy as possible, it'd be best if we didn't have to update all the callsites in JS and platform code, at least for core JS modules like `RCTDeviceEventEmitter`. So we'd like to implement this callable module pattern for bridgeless mode as well.
In this diff, I'm installing a global variable, `RN$registerCallableModule`, which will store the JS module name and factory function in C++. This can then be called from platform code (Java/Obj-C) to invoke a JS function on a module using the existing APIs (`context.getJSModule()` on Android, `enqueueJSCall()` or similar on iOS).

Summary:
Right now we use `BatchedBridge.registerLazyCallableModule` for all JS modules except for `HMRClient`, which uses `registerCallableModule` instead (takes the module itself instead of a function that returns it). I'm standardizing on `registerLazyCallableModule` so that it will be easier to swap out the implementation later for bridgeless mode.
The only reason I could think why we wouldn't want to do this is if we're relying on some side effect of `require('HMRClient')` when setting up JS, but there don't seem to be any side effects in that module that I can see.

Summary:
Running a PROD JS bundle with a DEV binary used to redbox with Fast Refresh on. The error said "HMRClient is not a registered callable module".
This isn't a new issue: https://www.google.com/search?q=%22hmrclient%20is%20not%20a%20registered%22. However, now it happens every time because `setup()` is now called unconditionally in a DEV native build.
Because a combination of DEV binary + PROD JS is technically possible, I'm adding a tiny shim that will make it a no-op instead of crashing. It will also explain what's wrong if you *intentionally* try to turn on Fast Refresh.

Summary:
In bridgeless mode we don't want to set up the batched bridge, which is set up as part of InitializeCore. Instead of deleting InitializeCore completely, let's just skip this step if we're in bridgeless mode, which we'll detect using a global variable set on the runtime from cpp (`RN$Bridgeless`).
This way you still get an error if the bridge is somehow not set up properly when you're not in bridgeless mode (it won't fail silently).

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
I'm changing all callsites to use either global or scoped perf logger explicitly in one diff.
`GlobalPerformanceLogger` is basically a singleton
`scopedPerformanceLogger` is scoped to the React tree by using a React Context

Summary: Split up InitializeCore into a bunch of modules. The idea here is to make it easier for apps to just get the initialization logic they want and leave behind what they don't; for example, if you don't want the Map/Set polyfills, instead of requiring InitializeCore you can require the modules you want from it.
