kunit: Support skipped tests

Browse Source 
The kunit_mark_skipped() macro marks the current test as "skipped", with
the provided reason. The kunit_skip() macro will mark the test as
skipped, and abort the test.

The TAP specification supports this "SKIP directive" as a comment after
the "ok" / "not ok" for a test. See the "Directives" section of the TAP
spec for details:
https://testanything.org/tap-specification.html#directives

The 'success' field for KUnit tests is replaced with a kunit_status
enum, which can be SUCCESS, FAILURE, or SKIPPED, combined with a
'status_comment' containing information on why a test was skipped.

A new 'kunit_status' test suite is added to test this.
