Introduce new cache type, the Mesa-DB. This is a single-file read/write
cache that is based on the read-only Fossilize DB cache. Mesa-DB supports
cache size capping. It's a much more efficient cache than the multi-file
cache because Mesa-DB doesn't have the inode overhead. The plan is to make
Mesa-DB the default cache implementation once it will be deemed as stable
and well tested. For now users have to set the new MESA_DISK_CACHE_DATABASE
environment variable in order to active the Mesa-DB cache.
Mesa-DB cache is resilient to corrupted cache files and doesn't require
maintenance from users and developers. The size capping is implemented
by evicting least recently used cache items and compacting the cache
database files with the evicted entries. In order to prevent frequent
compaction of the cache, at minimum a half of cache is evicted when cache
is full.

This was disabled ages ago because it provoked bugs between us and
xserver about context creation attributes, hopefully those servers are
out of circulation by now, let's find out.

Instead of having stencil writes as an out parameter of the optimization
function, we add a new write_enable field for stencil that's equivalent
to the similarly named field for depth. This doesn't mean drivers must
actually support disabling stencil writes independently but the
information may be helpful on some hardware.

This feature allows shaders to use pointers to buffers which may
not be bound via descriptor sets. Access to these buffers is done
via global intrinsics.
Because the buffers are not accessed through descriptor sets, any
live buffer flagged with VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT_KHR
can be accessed by any shader using global intrinsics, so the driver
needs to make sure all these buffers are mapped by the kernel when
it submits the job for execution.
We handle this by tracking if any draw call or compute dispatch in
a job uses a pipeline that has any such shaders. If so, the job is
flagged as using buffer device address and the kernel submission
for that job will add all live BOs bound to buffers flagged with the
buffer device address usage flag.

There's been several requests to push the release back a bit to allow
more time in the 22.2 cycle, so we'll bump by two weeks. This adds an
extra 22.1 release to the schedule as well, due to the move.

Utgard supports MSAA 4x, so wire it up.
RSW bits were already REd by Luc, the only remaining part was storing
non-resolved buffers, reloading them (including for depth/stencil) and
doing MSAA resolve.
To store non-resolved buffer we need to set mrt_pitch and mrt_bits
registers in WB, and to resolve non-resolved buffer we need to reload
it into individual samples and then write out with mrt_bits = 0, it's
now done by lima blitter.
We also need to do resolve on transfer_map() of multi-sampled buffers,
so utilize u_transfer_helper for that.
As a side fix, it turns out that our wb_reg definition wasn't correct,
'zero' isn't always zero, it's set if we need to swap channels, and
it goes before mrt_bits. mrt_bits actually enables multiple MRTs,
so this commit renames 'zero' to 'flags' and changes its position.
If mrt_bits == 0 and MSAA is enabled, GPU does resolve
in place, to expose this functionality we set PIPE_CAP_SURFACE_SAMPLE_COUNT.
Fixes dEQP-GLES2.functional.multisample.*
