This is necessary to ship new versions of ANGLE and to add more platform coverage (e.g. Arm64).

Logs for last builds are still available: https://github.com/dotnet/Silk.NET/actions/workflows/angle.yml

Essentially when cloning recursively and building we quickly passed the actions limits. If we can figure out a way to cross-compile (a la zig cc) on just Windows, we can use our self-hosted runner. Otherwise, I'm not sure what can be done to combat this.
