fixed build type when downloading hermes artifacts (#51283)

Summary:
Hermes build-type was hardcoded to 'release' in the previous version of the prebuild scripts.

This commit fixes this so that we can provide a build-type for hermes when downloading prebuilt tarballs.

- Cleaned up parameters in hermes.js
- Updated with buildType parameter when suitable
- Fixed some function names
- Updated version file so that it contains build type
- Removed version file when using a local tarball

## Changelog:

[IOS] [FIXED] - Fixed resolving build type when downloading hermes artifacts
