…se `export` syntax. (facebook#48763)

Summary:
Pull Request resolved: facebook#48763

## Motivation
Modernising the react-native codebase to allow for ingestion by modern Flow tooling.

## This diff
- Updates files in `Libraries/BugReporting`, `Libraries/vendor`, `Libraries/Vibration` and `Libraries/YellowBox` to use `export` syntax
  - `export default` for qualified objects, many `export` statements for collections (determined by how it's imported)
- Appends `.default` to requires of the changed files.
- Updates Jest mocks.
- Updates the public API snapshot (intented breaking change)

Changelog:
[General][Breaking] - Files inside `Libraries/BugReporting`, `Libraries/vendor`, `Libraries/Vibration` and `Libraries/YellowBox` use `export` syntax, which requires the addition of `.default` when imported with the CJS `require` syntax.
