Align creation of FabricUIManager with bridge

Summary:
- Bridgeless is using a deprecated FabricUIManager constructor which bridge doesn't use, and is the only one using it, this diff migrated bridgeless to use the same FabricUIManager constructor as bridge
- Remove static view config check (mShouldDeallocateEventDispatcher), instead use Bridgeless check since SVC is enabled in Bridgeless but not in Bridge.

Changelog:
