Moving timing logic out of TimingModule and into a new class
Summary: Decoupling the logic for managing timers from the native module interface in TimingModule. I'm doing this so we can more easily share this logic with bridgeless RN, which won't use a native module for timers but instead will define the bindings with JSI. This diff just moves things around and doesn't change any of the behavior. Reviewed By: PeteTheHeat Differential Revision: D17282187 fbshipit-source-id: ef54254dd0c7e2f6e294e9ae5a7d4b010f98de2e
