When reviewing test output after a failure, it's often quite difficult
to work out the order and timing of events, and to correlate test suite
output with kernel logs.
This adds timestamps to ZTS output to help with this, in three places:
- all of the standard log_XXX functions ultimately end up in _printline,
which now prefixes output with a timestamp. An escape hatch
environment variable is provided for user_cmd, which often calls the
logging functions while also depending on the captured output.
- the test runner logging function log() also now prefixes its output
with a timestamp.
- on failure, when capturing the kernel log in zfs_dmesg.ksh, the "iso"
time format is requested.

This commit changes the workflow of the github actions.
We split the workflow into different parts:
1) build zfs modules for Ubuntu 20.04 and 22.04 (~25m)
2) 2x zloop test (~10m) + 2x sanity test (~25m)
3) functional testings in parts 1..5 (each ~1h)
- these could be triggered, when sanity tests are ok
- currently I just start them all in the same time
4) cleanup and create summary
When everything is fine, the full run with all testings
should be done in around 2 hours.
The codeql.yml and checkstyle.yml are not part in this circle.
The testings are also modified a bit:
- report info about CPU and checksum benchmarks
- reset the debugging logs for each test
- when some error occurred, we call dmesg with -c to get
only the log output for the last failed test
- we empty also the dbgsys

Porting Notes:
- Enable internal log for DEBUG builds and in zfs-tests.sh.
- callbacks/zfs_dbgmsg.ksh - Dump interal log via kstat.
- callbacks/zfs_dmesg.ksh - Dump dmesg log.
- default.cfg - 'Test Suite Specific Commands' dropped.
