Split functional testings via github action matrix

This commit changes the workflow of the github actions.

We split it into three parts this way:
1)  build zfs modules (~15m)
2a) zloop tests (~10m)
2b) sanity tests (~25m)
2c) functional testings via five parts (each ~1h)
3)  cleanup zfs modules of step 1

When everything runs fine, the full run should be done in
about 2 hours. The checkstyle.yml is left untouched and
should be okay.

The testings are also modfied a bit:
- report info about CPU and checksum benchmarks
- remove workaround for cloud-init bug (issue 12644)
- add Ubuntu 22.04 for build and zloop tests
- the sanity and functional tests for 22.04 needs some more work
