twister: add option cleanup all tests

add 2 choices for '--runtime-artifact-cleanup' option,
'passing' to delete artifacts of passing tests,
'all' to delete artifacts of both passing tests
and failing tests

keep testcase_extra.config, it contains some extra Kconfig
needed for the tests and they is only generated first time
when run retry failed
