Build on Github Action test-macOS frequently fail due machine run out of disk space

[jakecastelli]

The Github Actions start to fail frequently on test-macOS build step due to the current build on mac is about 18GB which seems more than the allocated disk space on the runner (14GB limit IIRC). See this for a failure example:

test-macOS
You are running out of disk space. The runner will stop working when the machine runs out of disk space. Free space left: 47 MB

This currently impacts all the Pull Requests on nodejs cores.

GitHub only offers 14 GB of storage on their "standard" runners: https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories

Unlike for Linux and Windows, GitHub do not offer more storage on their "large" (i.e. paid) runners (still 14 GB for macOS): https://docs.github.com/en/actions/using-github-hosted-runners/using-larger-runners/about-larger-runners#specifications-for-general-larger-runners

Apparently the amount of available disk space available decreased (albeit still with 14 GB available and therefore meeting GH's documented available storage) with GH's 20240827.4 macOS runner image -- there's a general discussion around this over in: actions/runner-images#10511

I'm aware of various hacks/scripts for the Ubuntu runners to reclaim space (see actions/runner-images#10386) but not for macOS.

I do not know if there is anything we can do to reduce the size of Node.js macOS builds -- they appear to be significantly larger than their Linux equivalents.

Should we disable macOS jobs for now?

The problem is that we would have 0 CI coverage for arm64 macOS if we do it (Jenkins CI currently only tests on x64)

[jakecastelli]

Do we need Android sdk for macOS arm64 build? Any chance we can temporarily remove it (with a quick patch) from the test-macOS job? seems like it can claim back ~12GB storage space.
