Enable cmd-buf local memory update CTS tests on L0

The CTS tests for updating local memory in command-buffer kernel
commands are currently skipped on Level-Zero. This feature is now
available in L0 drivers so the tests can be enabled.

There is a failure in `LocalMemoryUpdateTest.UpdateParametersSmallerLocalSize`
with incorrect results. Mark the individual test as failed as it needs further
investigation.
