Restore original tests for TypedArrays and optimize files

Browse Source 
- optimize file names
- BigInt folder for TAs.from and of
- copy tests preparing for bigint
- copy ta prototype methods for bigint
- Use an exclusive harness for bigint typedarrays
- add features
- use proper harness
- use preper harness
- Restore original tests for TypedArrays
- final fixes
- fix includes
