ci: add check-build job to require make build to pass on prs (#19460)

ethanndickson · web-flow · commit 444874d9db76 · 2025-08-21T17:59:18.000+10:00
We've had `build` fail on main one or two times, and it's easily
preventable by just running `make build` on PRs.

I didn't add `build` to required as it's already pretty complex, and
we'd be making it more complex by skipping half of it when not on
coder/coder main.
