NO-JIRA: rework GHA jobs cache config

- Use simple path instead of earlier workarounds.
- Add cleanup step instead to purge some output.
- Change back to single shared cache, reduces number and combined size
  of caches, Checks job usually completes first and contains superset.
- Change the intial key prefix so as to force a new cache
