Now that we can conveniently map between GEM handles and struct anv_bo
pointers, we can use a simple bitset for residency tracking instead of
the complex hash set. This shaves about 3% off of a CPU-limited example
running with the Dawn WebGPU implementation.

This makes a number of changes to the current API:
1. Everything is renamed to anv_device_* instead of anv_bo_cache_*
because the BO cache is soon going to be the sole BO allocation path
and not some special case to make import/export work.
2. Drop the cache parameter. It's totally redundant with the device
and just annoying to keep typing.
3. Rework flags so that they go the convenient direction for usage in
ANV rather than whichever awkward way the i915 specified it to
maintain backwards compatibility. This also gives us the
opportunity to set some defaults.
4. Add flags for mapping and coherency.

The growing algorithms for the softpin case and the userptr version are
almost entirely different. Having this weird join doesn't make the code
more comprehensible. This rework does a few things:
1. Move the comment about 48-bit addresses to anv_device_init where we
actually unset the EXEC_OBJECT_SUPPORTS_48B_ADDRESS flag.
2. Separate the paths in anv_block_pool_expand_range so it's easier to
see what happens in the two different cases.
3. Use the anv_block_poo::bos array for storing all allocated BOs in
both paths rather than using the cleanup list in both paths. This
lets us make the cleanups array only used for mmaps of the memfd for
the userptr case.

Instead of depending on a mutable BO in the state pool for handling
growing state pools, add a concept of "wrapper" BOs which just wrap an
actual BO. This way, the wrapper can exist once for all of time and we
can put it in relocation lists even if the actual BO it references gets
swapped out.

We're not THAT strapped for space that we can't burn one extra bit for

We have to go through and rewrite them all anyway so it doesn't do us
any good to put them in the list in anv_reloc_list_add. Also, for state
pools the handles are likely wrong by the time vkQueueSubmit is called.

Previously, we would read the offset from the BO in anv_reloc_list_add
to generate the presumed offset and then again in the caller to compute
the 64-bit address to write into the buffer. However, if the offset
somehow changed between these two points, the presumed offset would no
longer match the written offset. This is unlikely to actually ever be a
problem in practice because the presumed offset gets recorded first and
so if the written address is wrong then the presumed offset is almost
certainly wrong and the relocation will trigger. However, it's much
safer to simply have anv_reloc_list_add return the 64-bit address.

This lets us do less allocation because the anv_bo's are now embedded in
the sparse array and it also allows lock-free translation from GEM

On gen11 and older, compressed images are tiled and aligned to 4K. On
gen12 this 4K alignment restriction was removed. However, only aligning
the fast clear color buffer to 64B (a cacheline, as it's on the
documentation) is causing some bugs where the fast clear color is not
converted during the fast clear operation. Aligning things to 4K seems
to fix it.

allow the test to handle expected failures like this. If that plan works

In 0e4a75f917, Ken added a flag brw_stage_prog_data which indicates
whether any UBO pulls ever occur. Unfortunately, he neglected to set
the bit in the vec4 back-end. This was fine at the time because the
optimization was intended for iris which does not support gen7 and using
the vec4 back-end on Gen8+ requires an environment variable. We want to
use this in Vulkan which does support Gen7 so we want the information
from the vec4 back-end as well as scalar.
