radv: enable timestampComputeAndGraphics

Commit bfee9866 "radv: Use RELEASE_MEM packet for MEC timestamp query."
added WriteTimestamp handling for compute queues but forgot to flip
the flag.

Tested with DOOM (by me) and CTS (by Bas), but without verification
that these tests actually use timestamps on compute queues.
