Fix Apple and Android tools for m137

[pblazej]

• Fixes Android patches (mocks, prefixing)
• Adds Apple prefix patch
• Adds some CI infrastructure that binds "aggregate" apple(_prefixed) targets with xcframework stuff
  • I avoided the full-matrix approach here, as it's both wasteful (multiple pulls/syncs), plus the framework still needs some post-processing

@pblazej pushed fixes for the android prefixed build

Whoops, forgot to mention that the VERSION file holds the commit that the CI uses by default. I've updated the commit to point at the blaze/m137-patching now for testing.

Yup @davidliu it does the trick https://github.com/webrtc-sdk/webrtc-build/actions/runs/16111693894. Thanks a lot for taking a look! It should be ready for integration testing on Android then, right?

[davidliu]

I ran through some small testing with the build last week and seemed to work fine. Should be good to go.

BTW @davidliu which platforms are actually used here (I mean linux and rasp ones)

windows_x86_64, windows_arm64, macos_x86_64, macos_arm64, ubuntu-18.04_x86_64, ubuntu-20.04_x86_64, ubuntu-22.04_x86_64, ubuntu-18.04_armv8, ubuntu-20.04_armv8, raspberry-pi-os_armv6, raspberry-pi-os_armv7, raspberry-pi-os_armv8, android, android_prefixed, ios

I'll be probably doing another round of cleanup + final Apple script.

[pblazej]

@hiroshihorie I'm almost there with the build script, fixing the paths and misc stuff. Feel free to take a look, especially at global configs and build flags - is it 100% consistent with what you've used?

Once we get the artifact, we can try automating the push to https://github.com/livekit/webrtc-xcframework, or at least use consistent release numbers (based on tags like @davidliu did here) with Android, still pushing to the above repo manually and copying the hash, etc.

[pblazej]

Looks like it builds for iOS 🎉 https://github.com/webrtc-sdk/webrtc-build/actions/runs/16170404165 so the rest is a matter of the script itself

[pblazej]

We can do some cleanup in this file, mostly unused platforms, then remove "old" macOS/iOS stuff from run.py
