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.
