Refactor test framework integration and update package dependencies

- Removed Mocha as a test runner and replaced it with Pyxpecto for JavaScript and Python Fable compilers.
- Updated package.json to reflect the removal of Mocha and adjusted test scripts to use Node directly.
- Added conditional compilation directives to support Pyxpecto across different Fable compilers.
- Cleaned up test files by removing unnecessary Mocha references and ensuring compatibility with Pyxpecto.
- Introduced ignore tests for AsyncResultOption under specific compiler conditions.
