drm/nouveau: allow allocating NVDEC channels via abi16

Add NOUVEAU_FIFO_ENGINE_NVDEC to the abi16 uAPI and accept it in
channel allocation, mapping it to the NVDEC engine runlist.

Skip the Turing copy-engine workaround object for NVDEC channels: the
copy engines are not part of the NVDEC runlist, so the workaround
object cannot be instantiated on such channels (and is not needed
there).

This is required for NVK to implement Vulkan Video H.264 decode on top
of the NVDEC engine:
