Summary:
To prepare for the new architecture, introduce the following enforcement:
* Defining `RCT_NEW_ARCHITECTURE` in the build flag automatically enables violation reporting
* At runtime, call RCTEnableNewArchitectureViolationReporting() to enable/disable reporting - it takes effect with the future violations
* When violation reporting is enabled:
* RCTWarnNotAllowedForNewArchitecture(): log warning about a violation, but doesn't assert
* RCTEnforceNotAllowedForNewArchitecture(): assert when a violation happen
Also in this commit:
* Add warning when RCTRegisterModule() is called as a side effect of RCT_EXPORT_MODULE(). Many modules still need this, so we can't enforce it yet.
* Add enforcement when the bridge is initialize, because the new architecture cannot have the bridge.
