MVKMTLBufferAllocation: Support private temp buffers.

Some buffers, particularly those used by tessellation, indirect
multiview, or occlusion queries, are never written or read from the
host. Keeping the relevant data in VRAM should improve performance by
reducing the need for the GPU to make expensive accesses over the PCI
bus.

VRAM is a scarce resource on discrete GPUs, but this is part of why we
marked the buffers volatile.
