 - convert usercopy kselftest to KUnit

 - disable usercopy testing on !CONFIG_MMU

 - add MODULE_DESCRIPTION() to core, list, and usercopy tests

 - add tests for assertion formatting functions - assert.c

 - introduce KUNIT_ASSERT_MEMEQ and KUNIT_ASSERT_MEMNEQ macros

 - fix KUNIT_ASSERT_STRNEQ comments to make it clear that it is an
   assertion

 - rename KUNIT_ASSERT_FAILURE to KUNIT_FAIL_AND_ABORT
