CI improvements (#230)

- llvm artifacts search, download and extract now in `get-llvm` action 
- `get-emsdk` action - clone, install, activate emsdk, so we don't need
to build `revive-builder` for this
- switch workflows to new actions
- `concurrency` for remaining workflows (cancel run if new run is
triggered)
- `target_commitish` for main release, fixes release commit 
- Run release workflow in PR without creating a release if PR is labeled
with `release-test`
