Change KUnit test output to better comply with KTAP v1 specifications
found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html.
1) Use "KTAP version 1" instead of "TAP version 14" as test output header
2) Remove '-' between test number and test name on test result lines
2) Add KTAP version lines to each subtest header as well
Note that the new KUnit output still includes the “# Subtest” line now
located after the KTAP version line. This does not completely match the
KTAP v1 spec but since it is classified as a diagnostic line, it is not
expected to be disruptive or break any existing parsers. This
“# Subtest” line comes from the TAP 14 spec
(https://testanything.org/tap-version-14-specification.html) and it is
used to define the test name before the results.
Original output:
TAP version 14
1..1
# Subtest: kunit-test-suite
1..3
ok 1 - kunit_test_1
ok 2 - kunit_test_2
ok 3 - kunit_test_3
# kunit-test-suite: pass:3 fail:0 skip:0 total:3
# Totals: pass:3 fail:0 skip:0 total:3
ok 1 - kunit-test-suite
New output:
KTAP version 1
1..1
KTAP version 1
# Subtest: kunit-test-suite
1..3
ok 1 kunit_test_1
ok 2 kunit_test_2
ok 3 kunit_test_3
# kunit-test-suite: pass:3 fail:0 skip:0 total:3
# Totals: pass:3 fail:0 skip:0 total:3
ok 1 kunit-test-suite

Commit 6d2426b2f258 ("kunit: Support skipped tests") switched to using
`enum kunit_status` to track the result of running a test/suite since we
now have more than just pass/fail.
This callsite wasn't updated, silently converting to enum to a bool and
then back.

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.

add debugfs support for displaying kunit test suite results; this is
especially useful for module-loaded tests to allow disentangling of
test result display from other dmesg events. debugfs support is
provided if CONFIG_KUNIT_DEBUGFS=y.
As well as printk()ing messages, we append them to a per-test log.
