drm/xe/bo: consider dma-resv fences for clear job
There could be active fences already in the dma-resv for the object
prior to clearing. Make sure to input them as dependencies for the clear
job.
v2 (Matt B):
- We can use USAGE_KERNEL here, since it's only the move fences we
care about here. Also add a comment.
