[PATCH 2/3] kunit: Rename KUNIT_ASSERT_FAILURE to KUNIT_ASSERT for readability

[Eric Chan <ericchancf@google.com>]

Both KUNIT_FAIL and KUNIT_ASSERT_FAILURE defined to KUNIT_FAIL_ASSERTION
with different tpye of kunit_assert_type. The current naming of
KUNIT_ASSERT_FAILURE and KUNIT_FAIL_ASSERTION is confusing due to their
similarities. To improve readability and symmetry, renames
KUNIT_ASSERT_FAILURE to KUNIT_ASSERT. Makes the naming consistent,
with KUNIT_FAIL and KUNIT_ASSERT being symmetrical.
Additionally, an explanation for KUNIT_ASSERT has been added to clarify
its usage.
