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.*

Currently stride, offset, modifier is obtained by invoking
lima_resource_get_handle() with WINSYS_HANDLE_TYPE_KMS.
Before commit 47f000c170 this path was working. Obtained handle
was simply ignored by DRI frontend and only requested data used.
After commit 47f000c170 such requests started to fail when
DRI is initialized using KMSRO and resource has no scanout data.
When lima_resource_get_param() is implemented, it will be used in
a first place to obtain resource data.

Some opengl features require shader recompilation to be implemented in
the mali400 and can only be detected at draw time. In some applications,
this could lead to recompiling shaders on every frame which could kill
performance. Introduce a shader cache to prevent this issue.
lima didn't have vertex shader recompilation yet but it is needed to
implement followup features, so include it here too.
Code heavily borrowed from the vc4 shader cache implementation.
One notable difference between the vc4 reference implementation and lima
is that lima still compiles the base shader at state creation time
without deferring it to the next draw (so that it stays compatible with
behaviour expected by unmodified shader-db, for example).

The reload texture descriptor needs to take care of the mipmap level

glCopyTexSubImage2D triggers the lima_blit function which ends in a draw.
A reload is necessary. The reload texture descriptor is always built with

There's a lot going on here (it's a ton of commits squashed together
since otherwise this would be impossible to review...)
1. We have a fast path for linear->tiled for whole (aligned) tiles, but we
have to use a slow path for unaligned accesses. We can get a pretty
major win for partial updates by using this slow path simply on the
borders of the update region, and then hit the fast path for the
tile-aligned interior. This does require some shuffling.
2. Mark the LUTs constant, which allows the compiler to inline them,
which pairs well with loop unrolling (eliminating the memory accesses
and just becoming some immediates.. which are not as immediate on
aarch64 as I'd like..)
3. Add fast path for bpp1/2/8/16. These use the same algorithm and we
have native types for them, so may as well get the fast path.
4. Drop generic path for bpp != 1/2/8/16, since these formats are
generally awful and there's no way to tile them efficienctly and
honestly there's not a good reason too either. Lima doesn't support any
of these formats; Panfrost can make the opinionated choice to make them
linear.
5. Specialize the unaligned routines. They don't have to be fully
generic, they just can't assume alignment. So now they should be nearly
as fast as the aligned versions (which get some extra tricks to be even
faster but the difference might be neglible on some workloads).
6. Specialize also for the size of the tile, to allow 4x4 tiling as well
as 16x16 tiling. This allows compressed textures to be efficiently tiled
with the same routines (so we add support for tiling ASTC/ETC textures
while we're at it)
