ilo: try unblocking a transfer with a staging bo When mapping a busy resource with PIPE_TRANSFER_DISCARD_RANGE or PIPE_TRANSFER_FLUSH_EXPLICIT, we can avoid blocking by allocating and mapping a staging bo, and emit pipelined copies at proper places. Since the staging bo is never bound to GPU, we give it packed layout to save space.
