Tested with a small use-after-free Vulkan test. It's pretty basic
for now but I think I will add status decoding support to report
more useful information.

It's been a very long time since this was useless because dmesg
required sudo access for a while.
This will be replaced by the new GPUVM fault interface which allows
to query from the kernel directly instead of trying to parse dmesg.

Fix regex pattern in zink_extensions to use proper escaping. While the original
code works, it relies on Python ignoring incorrect syntax and fallbacking to
passing through the escape. Current behaviour results in SyntaxWarning
whenever the code is used.

Add `PAN_MAX_AFBC_PACKING_RATIO` variable. If the ratio (size of the
packed resource) / (size of the sparse resource) * 100 is above that
value, we don't care about packing it.

Add `forcepack` flag that will force conversion to AFBC-packed right

After converting a texture from one modifier to another, there is
no reason to force the modifier to stay constant afterwards. Set
back `modifier_constant` to false because it is changed by
`resource_setup` as it is causing issues when implementing AFBC
packing.

Make sure we don't convert the texture for nothing by only
legalizing when creating a batch instead of on surface creation.
Also, to avoid recursive blit, we need to legalize the destination
resource before blitting.
Finally, make sure the resource has a sparse memory layout if
AFBC compressed. The GPU doesn't support rendering to a AFBC-packed
texture.

When the GPU is converting a texture from linear/tiled to compressed
AFBC, it uses a sparse memory layout. That means that the
superblocks are stored starting at intervals equal to the size of an
uncompressed superblock. When memory usage needs to be optimized, it
is possible to pack the resource by trimming each superblock as much
as possible. The GPU will still be able to read from these packed
textures, but won't be able to write directly to them. If the
layout is AFBC-tiled, the packing process will also de-tile as
tiled+packed is not supported by Mali GPUs.
No new modifier flag has been added as the absence of the
`AFBC_FORMAT_MOD_SPARSE` flag means the resource will be packed.

The compute shader is going through all the AFBC header blocks and
calculating the size of valid data by summing up the subblock
sizes (and taking into account solid color, uncompressed mode and
copy blocks). The result is written into the given buffer (array
of `pan_afbc_block_info`).
The size is rounded up to the alignment parameter directly in the
shader.

For an upcoming feature (AFBC packing), we're gonna run internal
compute shaders on resources. This commit just split the internal

For AFBC packing, we will need to have the stride of the resource
in terms of superblocks and the total number of blocks. It is
easier to pre-calculate once when initializing the resource layout.

None of those cases are expected to fallthrough, but should be unreachable.
Just break them so they get to the unreachable entry at the end.
