Ramanpreet Nara 6c5ac8036e Bridgeless Mode: Migrate modules away from invokeJS
Summary:
This diff removes all synthesize invokeJS = _invokeJS calls, and instead funnels them through synthesize callableJSModules = _callableJSModules. Now, all these NativeModules shouldn't have different branching in bridgeless mode vs bridge mode.

Summary:
This is an extension of D25449795. I searched for all usages of .eventDispatcher within NativeModules, and migrated them all to the Venice-compatible RCTModuleRegistry API.

Ramanpreet Nara 82187bfb6b Dispatch events even when there are no listeners
Summary:
## Rationale
For every 1 call to RCTNetworking.sendRequest, we execute 6 calls to RCTNetworking.addListener. This is followed by at least one call to RCTNetworking.removeListeners. Aside from incrementing and decrementing the `_listeners` integer, these two methods accomplish nothing else: RCTNetworking doesn't implement the `startObserving` and `stopObserving` methods.

This diff makes RCTEventEmitter dispatch events without looking at the listeners integer. In the future, this will allow us to stop making these ~8 unnecessary NativeModule calls for every Network request we send.

Scott Kyle 23717e48af Call stopObserving on correct queue
Summary:
Since `dealloc` can be called from any thread, this would result `stopObserving` being called on a different thread/queue than the specified `methodQueue`. We specifically encountered this issue with a module needing the main queue having its `stopObserving` called on a background queue.

Peter Argany c494d590fb Workarounds for two bridge methods: dispatchToJSThread and enqueueJSCall:
Summary:
To get `RCTNativeAnimatedModule` working bridgeless, I need to get `RCTEventDispatcher` working bridgeless.

To get `RCTEventDispatcher` working bridgeless, I need to support 2 new bridge methods:
- `- (void)enqueueJSCall:(NSString *)moduleDotMethod args:(NSArray *)args`
- `- (void)dispatchBlock:(dispatch_block_t)block queue:(dispatch_queue_t)queue;`

For (1) I copied the bridge impl exactly. For (2), the bridge only dispatches to JS thread, else uses `dispatch_async`. I only added support for dispatching to JS thread, callers can `dispatch_async` themselves if they want to.

Peter Argany 824e171117 Refactor HotModuleReloadClient setup call from bridge to RCTDevSettings
Summary:
This refactors some logic which sets up HMRClient in JS. The logic should live in RCTDevSettings, so it is shared in bridge/bridgeless mode.

This also means the logic will be compiled out when `RCT_DEV_MENU` is false.

Pieter De Baets e1577df1fd Move all header imports to "<React/..>"
Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.

Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Nick Lockwood 9ee1f37bad Added native event emitter
Summary:
This is a solution for the problem I raised in https://www.facebook.com/groups/react.native.community/permalink/768218933313687/

I've added a new native base class, `RCTEventEmitter` as well as an equivalent JS class/module `NativeEventEmitter` (RCTEventEmitter.js and EventEmitter.js were taken already).

Instead of arbitrary modules sending events via `bridge.eventDispatcher`, the idea is that any module that sends events should now subclass `RCTEventEmitter`, and provide an equivalent JS module that subclasses `NativeEventEmitter`.

JS code that wants to observe the events should now observe it via the specific JS module rather than via `RCTDeviceEventEmitter` directly. e.g. to observer a keyboard event, instead of writing:

    const RCTDeviceEventEmitter = require('RCTDeviceEventEmitter');
    RCTDeviceEventEmitter.addListener('keyboardWillShow', (event) => { ... });

You'd now write:

    const Keyboard = require('Keyboard');
    Keyboard.addListener('keyboardWillShow', (event) => { ... });

Within a component, you can also use the `Subscribable.Mixin` as you would previously, but instead of:

     this.addListenerOn(RCTDeviceEventEmitter, 'keyboardWillShow', ...);

Write:

    this.addListenerOn(Keyboard, 'keyboardWillShow', ...);

This approach allows the native `RCTKeyboardObserver` module to be created lazily the first time a listener is added, and to stop sending events when the last listener is removed. It also allows us to validate that the event strings being observed and omitted match the supported events for that module.

As a proof-of-concept, I've converted the `RCTStatusBarManager` and `RCTKeyboardObserver` modules to use the new system. I'll convert the rest in a follow up diff.

For now, the new `NativeEventEmitter` JS module wraps the `RCTDeviceEventEmitter` JS module, and just uses the native `RCTEventEmitter` module for bookkeeping. This allows for full backwards compatibility (code that is observing the event via `RCTDeviceEventEmitter` instead of the specific module will still work as expected, albeit with a warning). Once all legacy calls have been removed, this could be refactored to something more elegant internally, whilst maintaining the same public interface.

Note: currently, all device events still share a single global namespace, since they're really all registered on the same emitter instance internally. We should move away from that as soon as possible because it's not intuitive and will likely lead to strange bugs if people add generic events such as "onChange" or "onError" to their modules (which is common practice for components, where it's not a problem).
