chore(ci): switch most workflows to depot ci (#3352)

Continuing the trend of shifting away from GitHub services. Depot is
faster, and more reliable.

Avoiding docker + release workflows for now, as those have been a pain
in the ass to get correct.

Will check and see if we can ensure the logs/etc can be public.

I'm going to merge this, see how well it works, and if we're good delete
the matching github workflows
