Rob Hogan fc365f6e72 Flow: Prefer imported types from @babel/types over global BabelNode* types (#57752)
Summary:
Pull Request resolved: https://github.com/react/react-native/pull/57752

## Rationale
Flow lib defs that declare global types (available anywhere, without an `import`) must be referenced in `.flowconfig` and can't be maintained incrementally.  That's not too bad for very stable APIs and it's necessary for environment/runtime globals, but for 3P libraries it makes the lib defs much more difficult to maintain for little benefit (we have to import the runtime APIs anyway). Secondarily, it's a problem for generating TypeScript types, as TS doesn't declare any 3P library globally.

Babel is one of few cases where a library declares Flow globals - every one has an importable equivalent.

## This diff
Replaces usages of Babel global types across xplat/js with their `babel/types` equivalents

Alex Hunt a22ab422e8 Loosen JS API breaking change detection, improve Danger message (#54901)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/54901

At present, we're only using a rough heuristic for whether a code change to `ReactNativeApi.d.ts` is a breaking change. Introduce `POTENTIALLY_BREAKING` result level and update Danger warnings box.
