[macOS] Regeneration of bridgesupport files necessary

[HeikoKlare]

The bridge support files for macOS used to be regenerated for newer macOS SDK versions. This has not happened for quite a while and we have started to manually add entries for newer macOS SDKs to that file so that we can use the MacGenerator for JNI binding generation on new API.

I have tried to regenerate those files with the available documentation (in particular the according readme) but the results look quite different from what we have right now (different properties due to using aarch64 and a high number of changes), which then lead to the MacGenerator deriving code that has many compile errors.

We should thus do the regeneration of those files in a separate task including the necessary cleanup and maybe MacGenerator adaptations to be conforming with latest SDK versions and have fully auto-generated bridgesupport files again.

Looking at the following:

It seems that there have been times when there was a macOS version update where all the bridge support files > have been completely regenerated against a new macOS SDK. The last time was here:
