[EricWF]

This removes the Google hosted Linux buildkite builders. We have since moved all of them over to github actions.

Follow up changes will be sent for android.

I plan to commit this once the bots come back green.

Thanks a lot for the cleanup, this was on my list! This should allow dropping the GCE runners on Linux altogether, right? Might be worth recording that benefit in the commit message.

Sounds good. I'm working on moving the android builders too, and I'll be happy to help you move the mac builders too.
It should be pretty simple.

[EricWF]

Submitting before the bots come back so I can stop wasting resources.

LGTM, thanks!
