Summary:
This makes the RCTEvent protocol more generic to make it easier to use the event coalescing feature for type of events other than components. This does a few other improvements that will be useful in follow up PRs.
- Add `RCTComponentEvent` which is used instead of deprecated `[sendInputEventWithName:body:]` and remove that method completely (was only used at 2 places).
- Make `coalescingKey` optional for events that return NO from `canCoalesce`.
- Make `viewTag` optional for events that are not related to views.
- Fast path for events that return NO from `canCoalesce`.
- Add a missing test for event coalescing with different view tags.
Ended up making only one PR for all this since the changes are related and hard to separate.
**Migration**
Use a custom RCTEvent subclass with `[sendEvent:]` (preferred way to allow type safe events) or `RCTComponentEvent`.
**Test plan**
- Ran RCTEventDispatcher unit tests
- Tested manually in RNTester
