Copy Flow parser tests to prepare TypeScript Parser

Summary:
These files are directly copied from the flow parser to aid in reviewing the next two Diffs: D33080789 and D33081127.

The only things that were changed during the copy are the import/require paths to ensure this diff could ship independently. (For this diff, these tests will still test the flow parser instead of importing the typescript parser).

Changelog:
[Internal][Add] - Copy Flow parser tests to aid in Diff review

Reviewed By: RSNara

Differential Revision: D33136296
