Mark slow memcpy KUnit tests using test attributes. Tests marked as slow are as follows: memcpy_large_test, memmove_test, memmove_large_test, and memmove_overlap_test. These tests were the slowest of the memcpy tests and relatively slower to most other KUnit tests. Most of these tests are already skipped when CONFIG_MEMCPY_SLOW_KUNIT_TEST is not enabled. These tests can now be filtered using the KUnit test attribute filtering feature. Example: --filter "speed>slow". This will run only the tests that have speeds faster than slow. The slow attribute will also be outputted in KTAP. Note: This patch is intended to replace the use of CONFIG_MEMCPY_SLOW_KUNIT_TEST and to potentially deprecate this feature. This patch does not remove the config option but does add a note to the config definition commenting on this future shift.
