Summary:
On Hermes, RN can directly use the Promise from global w/o the need of polyfilling it.
PromiseRejectionTrackingOptions are extracted to its own file so it can be shared by
both codepaths and preserve the behaviors that it's only imported on dev.
Some zero-overhead type gymnastics are used to flow-type it properly.
Changelog:
[General] - made promise polyfill conditionalized on Hermes
