Remove {eventName}: true from ViewConfig validAttributes

Summary:
For every direct and bubbling event, RCTComponentData (iOS-only) creates a {eventName}: true entry in the component's ViewConfig validAttributes. This entry is unnecessary, and creates a discrepancy between ViewConfigs on iOS vs Android.

This diff removes this entry for all events to:
1. Reduce bloat in native ViewConfigs
2. Create consistency betweeen Android and iOS.
