llvmpipe_resource_map() may fail, e.g. when the DMA-BUF cannot be
mmap'ed. Handle the error, either by returning NULL or by asserting.
Asserting is done in places where there is no good way to bubble up
the error (and is done in other places already, e.g. in
init_scene_texture).

Seems like the multiview feature unlocked some tests that triggers a
previously unknown bug. This results in an assert triggering, but that
reveals a real, underlying issue.
A few of these doesn't trigger the assert, but still fails due to a GPU
hang.
Let's mark all of these as failures, to avoid holding back other MRs in
the mean time.

Rather than checking hwconfig items when using them, wait until after
devinfo has been fully initialized. This includes having workarounds
implemented.
We can then check if the hwconfig data and final Mesa initialization
agree. If the match fails, we need to investigate if Mesa or the
hwconfig data is wrong.
This code becomes a no-op when not on a release build.

We already have all the bits wired up to support both
VK_FORMAT_A4R4G4B4_UNORM_PACK16 and VK_FORMAT_A4B4G4R4_UNORM_PACK16_EXT
from VK_EXT_4444_formats, and were already setting the feature-flags for
them.
Let's also expose the extension, which should just work.

We were missing a couple of 4-bit formats, let's add them.
Vulkan 1.0 already requires VK_FORMAT_B4G4R4A4_UNORM_PACK16, which mapes
to PIPE_FORMAT_A4R4G4B4_UNORM, which we're currently missing support for.
But we can also support VK_FORMAT_R4G4B4A4_UNORM_PACK16, which maps to
PIPE_FORMAT_A4B4G4R4_UNORM. This format is optional, but there's no
reason we shouldn't expose support for it.

Without multiview, a shader that doesn't write to the any of the
extended FIFO attributes (pointsize and layer) can be used with either
FIFO format. This allows us to switch to the basic FIFO format when
using the no_psiz variant. In multiview vertex shaders, output offsets
depend on the FIFO format. Instead of trying to patch these in the
no_psiz variant, just don't do the optimization for now.

Two components to this: first we only issue fragment jobs for enabled
views. This prevents disabled layers from being cleared implicitly with
`LOAD_OP_CLEAR`, and also reduces overhead (these layers have no
primitives so the fragment job is wasted work). Second is hooking up the
view mask to vk_meta_clear.

In Valhall multiview, position/varying shaders are invoked once per
draw. Each invocation write separate outputs for all views. Fragment
processing is handled by the existing multilayer support. Note that
because the hardware only supports up to 8 views, we don't have to care
about the case where there are too many layers to fit in one tiler when
multiview is enabled.

In panvk we pass absolute view indices to the hardware, so we need to do
the conversion from compacted to absolute at some point. Emitting
absolute indices from nir_lower_multiview initially looks like the
simplest option, but nir_lower_io_to_temporaries will emit a write for
every element of array varyings. This results in unnecessary writes to
disabled views.

This is needed for implementing multiview in panvk, where the address
calculation for multiview outputs is not well-represented by lowering to
nir_intrinsic_store_output with a single offset.
The case where a variable is both per-view and per-{vertex,primitive} is
now unsupported. This would come up with drivers implementing
NV_mesh_shader or using nir_lower_multiview on geometry, tessellation,
or mesh shaders. No drivers currently do either of these. There was some
code that attempted to handle the nested per-view case by unwrapping
per-view/arrayed types twice, but it's unclear to what extent this
actually worked.
ANV and Turnip both rely on per-view outputs being assigned a unique
driver location for each view, so I've added on option to configure that
behavior rather than removing it.
