We access sysvals as if they were declared as a big struct containing
all the sysvals for all the stages in a pipeline. Declaring fields
as panvk_sysval_vec4 when we don't use all the components doesn't make
sense, so let's drop panvk_sysval_vec4 and declare exactly what we
need.
We also take this as an opportunity to split the graphics and compute
sysval structs.

We don't need to stop the panvk_buffer_desc objects to then emit the
UBOs/SSBOs descriptors at draw/dispatch time. We can simply prepare
them at bind time and cache the result, to make the
draw/dispatch preparation a simple memcpy.

We are about to put our sysvals in the push uniforms array, but before
we can do that, we need to store our dynamic storage buffers in a
dedicated UBO. We put this dynamic descriptor UBO after the dynamic
UBOs.

It's easier to reason about if dynamic uniform buffers (which have
a per-pipeline limit, and are cached at the command buffer level) are
placed at the end of the UBO array. It will also allow us to do a memcpy
instead of iterating over all sets to collect these dynamic UBOs.

Align16 is only used on Gfx9, while Align1 is used on Gfx11+. We can
decode both kinds of encodings in the same function with a simple
devinfo check. One snag is that the align16 encodings didn't have a
separate exec_type field, but we can just pass 0.
This lets us have a single function named brw_type_decode_for_3src,
which is much less of a mouthful.

In ancient days, we directly used the hardware register type encodings
throughout the compiler. As more GPU generations came out, encodings
shifted, and we moved to an abstract enum that we could encode/decode
to a particular GPU's hardware encoding. But there was no particular
meaning behind any particular value.
One downside to this approach is that we end up with switch statements
galore. Want to know a type's size? Switch. Convert a unsigned type
to a signed one? Switch. Get a type with the same base type, but
different bit size? Switch. This is both inefficient and inconvenient.
In contrast, nir_alu_type takes a nicer approach - the type encoding has
certain bits representing the base type, and others encoding the size of
the type. Switching base types or sizes is a simple matter of masking
out the relevant field and substituting a different one.
Tigerlake's encoding adopts a similar approach: two bits represent the
size as a 2-bit unsigned number n, where the bit size is (8 * 2^n).
Two more bits represent the base type. Past encodings were a bit ad hoc
as new data types were added over time, but Gfx12 is organized (mostly).
This patch converts our brw_reg_type enum over to a new system that's
patterned after the Tigerlake style (for easy conversion) while
deviating in a few ways that make our vector immediate type size
handling simpler. Should we add additional base types, we're likely
to continue deviating. Still, converting is much simpler.
Type size calculations (which are performed all the time) are now a
simple mask and shift, instead of a switch.
We also adopt the name BRW_TYPE_* instead of BRW_REGISTER_TYPE_* because
it's much shorter and easier to type. Similarly, we create new helper
functions named brw_type_* for working with these types, with a cleaner
naming convention. Legacy names still exist but will we dropped over
the next few patches as pieces get cleaned up.

Icelake removed the PLN instruction for interpolating fragment shader
inputs, instead adding a special "Native Float" (NF) data type which
was a 66-bit floating point data type that could only be used with the
accumulator. On Tigerlake, they dropped NF support in favor of just
doing the interpolation with MAD instructions.
We stopped using NF years ago (commit 9ea90aae1e),
instead just using the fs_visitor::lower_linterp() pass to emit MADs.
Since this existed only for a short time, and had very limited utility,
we drop it from the compiler. One downside is that we can no longer
disassemble Icelake shaders containing NF types properly, but I doubt
anyone really minds.

We were accidentally leaving XY_BLOCK_COPY_BLT's Source and Destination
MOCS fields set to 0 (Error: Reserved for Non-Use) on Gfx12.0 systems.
This was causing assert fails in debug builds, since we try to ensure
that we don't do that. In theory, MOCS 0 is supposed to be equivalent
to MOCS 2 (all the caching), but...we probably ought to use MOCS 3
(uncached). Every Gfx12.5+ platform requires it, so although there
isn't a note about Gfx12.0 needing that, it's possible that it does.
We're currently only using the blitter for DRI PRIME blits on Gfx12.0,
anyway, and I think we're flushing all the caches regardless.
This bug was somewhat obscure to hit:
- You need a hybrid graphics system with Gfx12.0 and some other GPU
- You have to be using "reverse PRIME", i.e. rendering on the integrated
GPU and displaying on the discrete one. This is not the common case.
- You have to be using a debug build.
No observable performance delta in GfxBench5 Car Chase (an arbitrary
program) when rendering on Alderlake GT1 and displaying on an Arc A770.
