This code shows up a little on profiling on Gfx12 and since it's only
a gfx8/9 workaround we might as well ifdef it out.

Setting the NIR options takes care of iris thanks to the common st/mesa
linking code, and updating brw_nir_link_shaders should handle anv.
The main effort here is updating remap_tess_levels, which needs to
handle vector stores, writemasking, and swizzling. Unfortunately,
we also need to continue handling the existing single-component
access because it's used for TES inputs, which we don't vectorize.
We could try to vectorize TES inputs too, but they're all pushed
anyway, so it wouldn't buy us much other than deleting this code.
Also, we do have opt_combine_stores, but not one for loads.
One limitation of using nir_vectorize_tess_levels is that it works
on variables, and so isn't able to combine outer/inner writes that
happen to live in the same vec4 slot (for triangle domains). That
said, it's still better than before.
For writes, we allow the intrinsics to supply up to the full size
of the variable (vec4 for outer, vec2 for inner) even if the domain
only requires a subset of those components (i.e. triangles needs 3).

This makes two relatively small changes, first it addes the encoding to
the xml delcaration, and switches the quote style. Second, it changes
the final newline. These seemed minor enough to not warrent patches to

On DG2 the HW will fetch the binding entries into the cache
for every single thread when a compute walker is dispatched,
wiping out the advantages of the cache prefetch.
The spec also advises to not do a cache prefetch when we have more than
31 binding table entries, but most real world applications will never
hit that limit.

This should make it a lot more clear how depth clip enables work.
Annoyingly, because of the way they originally worked in Vulkan 1.0,
it's dependent on the depth clamp if the state isn't set in the pipeline
and isn't declared dynamic. The enum is explicitly set up so that
drivers don't need to be aware of this change unless they already
implement VK_EXT_extended_dynamic_state3. If depth clamp/clamp are not
dynamic, depth clip will be either TRUE or FALSE which map to 1/0 so the
field can still be treated as a boolean.
