ci: allow POCL build on push to populate cache (#2741)

Browse source 
Split the `tests` job into three separate jobs:
- `check-triggers`: Parses triggers on pull requests.
- `build-pocl`: Builds and caches POCL. Runs on pushes to any branch or
when tests are triggered on PRs.
- `tests`: Runs the tests using the cached POCL.

This allows the POCL build to run on pushes to populate the cache,
ensuring subsequent PRs have a cache hit and don't need to rebuild POCL.
