[ReactNative] Move module info from bridge to RCTModuleData

Summary:
@public

The info about bridge modules (such as id, name, queue, methods...) was spread
across arrays & dictionaries on the bridge, move it into a specific class.

It also removes a lot of information that was statically cached, and now have
the same lifecycle of the bridge.

Also moved RCTModuleMethod, RCTFrameUpdate and RCTBatchedBridge into it's own
files, for organization sake.

NOTE: This diff seems huge, but most of it was just moving code :)

Test Plan:
Tested UIExplorer & UIExplorer tests, Catalyst, MAdMan and Groups. Everything
looks fine.
