Eric Chan ebf51e460e kunit: Introduce KUNIT_ASSERT_MEMEQ and KUNIT_ASSERT_MEMNEQ macros 
Introduces KUNIT_ASSERT_MEMEQ and KUNIT_ASSERT_MEMNEQ macros
to provide assert-type equivalents for memory comparison.
While KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ are available for
expectations, the addition of these new macros ensures that assertions
can also be used for memory comparisons, enhancing the consistency and
completeness of the kunit framework.
