If we expect device losts (breadcrumb debug), we need to use DEVICE uncached/coherent,
since we might not be able to flush GPU caches properly.
We also need to remove the idea of being able to copy out the control
block back to host. This is too brittle and we should instead just place
the control block in PCI-e BAR instead. Rethink how we pass messages
from GPU to CPU to make it more robust.

Mesa RADV translates these legacy entrypoints to the 2 variants. Using
them directly will cost a bit less CPU cycles.

We will need to consider some form of budgeting, so make sure that all
allocation and freeing is done in a central place.

This is still useful as a low-level memory allocation function when
we don't want to bother with buffer offsets or D3D12 validation.
