This gets rid of quite a bit of CPU/GPU sync on frequent vertex buffer

This is similar to the previous commit only for HiZ. For HiZ, apart
from everything looking different, there is really only one functional
change: We now track the ISL_AUX_STATE_COMPRESSED_NO_CLEAR state.
Previously, if you rendered to a resolved slice of the miptree and then
did a fast-clear with a different clear color, that slice would get
resolved even though it hadn't been fast-cleared. Now that we can track
COMPRESSED_NO_CLEAR, we know that it doesn't have any blocks in the
"clear" state so we can skip the resolve.

This commit reworks the resolve tracking for CCS and MCS to use the new
isl_aux_state enum. This should provide much more accurate and easy to
reason about tracking. In order to understand, for instance, the
intel_miptree_prepare_ccs_access function, one only has to go look at
the giant comment for the isl_aux_state enum and follow the arrows.
Unfortunately, there's no good way to split this up without making a
real mess so there are a bunch of changes in here:
1) We now do partial resolves. I really have no idea how this ever
worked before. So far as I can tell, the only time the old code
ever did a partial resolve was when it was using CCS_D where a
partial resolve and a full resolve are the same thing.
2) We are now tracking 4 states instead of 3 for CCS_E. In particular,
we distinguish between compressed with clear and compressed without
clear. The end result is that you will never get two partial
resolves in a row.
3) The texture view rules are now more correct. Previously, we would
only bail if compression was not supported by the destination
format. However, this is not actually correct. Not all format
pairs are supported for texture views with CCS even if both support
CCS individually. Fortunately, ISL has a helper for this.
4) We are no longer using intel_resolve_map for tracking aux state but
are instead using a simple array of enum isl_aux_state indexed by
level and layer. This is because, now that we're tracking 4
different states, it's no longer clear which should be the "default"
and array lookups are faster than linked list searches.
5) The new code is very assert-happy. Incorrect transitions will now
get caught by assertions rather than by rendering corruption.

This also removes an unneeded brw_render_cache_set_check_flush() call.
We were calling it in the case where the surface got resolved to satisfy
the flushing requirements around resolves. However, blorp now does this
itself, so the extra is just redundant.

This commit adds a new unified interface for doing resolves. The basic
format is that, prior to any surface access such as texturing or
rendering, you call intel_miptree_prepare_access. If the surface was
written, you call intel_miptree_finish_write. These two functions take
parameters which tell them whether or not auxiliary compression and fast
clears are supported on the surface. Later commits will add wrappers
around these two functions for texturing, rendering, etc.

This enum describes all of the states that a auxiliary compressed
surface can have. All of the states as well as normative language for
referring to each of the compression operations is provided in the
truly colossal comment for the new isl_aux_state enum. There is also
a diagram showing how surfaces move between the different states.
