Migrated components to export syntax (part 2) (#48767)

Summary:
Pull Request resolved: #48767

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

## This diff
- Updates a handful of components in `Libraries/Components` 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 test files.
- Updates the public API snapshot (intented breaking change)

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