Update code to conform to the newer version of pylint available in
ubuntu-22.04, with few exceptions:
- disabled `import-outside-toplevel` for `main()` in
`jerry_client.py`
- disabled `consider-using-with` for the logfile of `TestSuite` in
`test262-harness.py` as using `with` is not practical in that case
Update test262-harness.py to use argparse instead of the now deprecated
optparse
Rename variables in jerry_client_main.py that redefined python builtins
or shadowed variables from an outer scope
Update python files to use f-stirngs
Add minimum python versions (3.6 and 3.8) to the CI jobs: without it the
default python version did not support the `with` statement for
`subprocess.Popen` used in `build.py` on macos, or in some cases f-stirngs
Remove `from __future__` imports that are no-ops in python 3
Remove shebang from non executable files
Re-enable most pylint checkers, except `missing-docstring`
