Move lib/test_uuid.c to lib/tests/uuid_kunit.c and convert it to use KUnit. This change switches the ad-hoc test code to standard KUnit test cases. The test data remains the same, but the verification logic is updated to use KUNIT_EXPECT_* macros. Also remove CONFIG_TEST_UUID from arch/*/configs/* because it is no longer used. The new CONFIG_UUID_KUNIT_TEST will be automatically enabled by CONFIG_KUNIT_ALL_TESTS.
