chore: move experimental setup steps to composite action (#170496)
tool-test-general.yml had a lot of gnarly, but sharable code. Moving to
a shared, composite workflow.

updates:
- removed the "flutter/" working folder while running; keep the code in
the workspace
- moved android and pub-cache to /opt/
- switched to `flutter pub get` as the last step
- caching still works; but I think we could do better.
