1ec4e568de radv: abstract queue family away from queue family index.
If we introduce another queue type (video decode) we can have a
disconnect between the RADV_QUEUE_ enum and the API queue_family_index.

currently the driver has
GENERAL, COMPUTE, TRANSFER which would end up at QFI 0, 1, <nothing>
since we don't create transfer.

Now if I add VDEC we get
GENERAL, COMPUTE, TRANSFER, VDEC at QFI 0, 1, <nothing>, 2
or if you do nocompute
GENERAL, COMPUTE, TRANSFER, VDEC at QFI 0, <nothing>, <nothing>, 1

This means we have to add a remapping table between the API qfi
and the internal qf.

This patches tries to do that, in theory right now it just adds
overhead, but I'd like to exercise these paths.

v2: add radv_queue_ring abstraction, and pass physical device in,
as it makes adding uvd later easier.
v3: rename, and drop one direction as unneeded now, drop queue_family_index
from cmd_buffers.

fd8210f27e radv: Try to do a better job of dealing with L2 coherent images.
Only try to invalidate L2 if we actually hit one of the incoherent images.

Note we may actually insert some extra flushes at the end of a command
buffer so that we may asume the caches are clean the start of the next
command buffer. However, on average I think that case is uncommon
enough that being able to make assumptions at the start of a cmdbuffer
is beneficial. Especially since MSAA is somewhat rare in more recent
games.

The existing code handled the case where the new definition of the

This commit adds a check to handle the reverse case: the new def
is smaller than the old one (= so writing using the merged macro
would affect the next fields).

The affected fields are:
* LGKM_CNT (in SQ_WAVE_IB_STS)
* DONUT_SPLIT (in VGT_TESS_DISTRIBUTION)
* HEAD_QUEUE (in GDS_GWS_RESOURCE)

DONUT_SPLIT is the only one used by radeonsi/radv.
