Instead of having aux usage and ANV_AUX_USAGE_DEFAULT to mean "give me
something reasonable" we now use anv_layout_to_aux_usage whenever a
layout is available. If a layout is available, we ignore the aux_usage
parameter. For the cases where we have an explicit aux usage such as
clears and aux ops, we have a new ANV_IMAGE_LAYOUT_EXPLICIT_AUX layout.

If we don't have HiZ, then anv_layout_to_aux_usage will return NONE for
both layouts. If the two layouts are the same, they will get the aux
usage. In either case, the code below will give us ISL_AUX_OP_NONE and
we'll return without doing anything.

This is quite a bit cleaner because we now sync the clear values at the
same time as we do the fast clear. For loading the clear values into
the surface state, we now do it once when we handle the LOAD_OP_LOAD
instead of every subpass.

This requires us to ditch the VkAttachmentReference struct in favor of
an anv-specific struct. However, we can now easily identify from just
the subpass attachment what kind of an attachment it is. This will make
iteration over anv_subpass::attachments a little easier in some case.

This moves the decision out of begin_subpass and into BeginRenderPass
like the decision for color clears. We use a similar name for the
function for depth/stencil as for color even though no aux usage is
really getting computed.
v2 (Jason Ekstrand):
- Don't always disable HiZ clears by accident
- Use the initial layout to decide whether to do fast clears

This is similar to blorp_gen8_hiz_clear_attachments except that it takes
actual images instead of trusting in the already set depth state.

This doesn't really change much now but it will give us more/better
control over clears in the future. The one interesting functional
change here is that we are now re-emitting 3DSTATE_DEPTH_BUFFERS and
friends for each clear. However, this only happens at begin_subpass
time so it shouldn't be substantially more expensive.

This is a bit less awkward than passing in the subpass because it means
we don't have to extract the subpass id from the subpass.

This seems slightly more correct because it means that the flushes
happen before any clears or resolves implied by the subpass transition.

Previously, we just used all the channels regardless of the format.
This is less than ideal because some channels may have undefined values
and this should be ok from the client's perspective. Even though the
driver should do the correct thing regardless of what is in the
undefined value, it makes things less deterministic. In particular, the
driver may choose to fast-clear or not based on undefined values. This
level of nondeterminism is bad.

This fixes a pile of hangs caused by the recent shuffling of resolves
and transitions. The particularly problematic case is when you have at
least three attachments with load ops of CLEAR, LOAD, CLEAR. In this
case, we execute the first CLEAR followed by a MI memcpy to copy the
clear values over for the LOAD followed by a second CLEAR. The MI
commands cause the first CLEAR to hang which causes us to get stuck on
the 3DSTATE_MULTISAMPLE in the second CLEAR.
We also add guards for BLORP to fix the same issue. These shouldn't
actually do anything right now because the only use of indirect clears
in BLORP today is for resolves which are already guarded by a render
cache flush and CS stall. However, this will guard us against potential
issues in the future.
