We don't need to look at the framebuffer state and record how many color
buffers to write. Instead, we can deduce which color buffers are enabled
from spi_shader_col_format, which already does the right thing.
So PS epilogs only need a single bool flag that determines whether all
enabled color buffers should be written.

This adds an option into the prolog key to replace frag_coord.xy with
pixel_coord when sample shading is disabled, which is most of the time.
This reduces the number of input VGPRs.
It's already implement in ac_nir_lower_ps_early for monolithic shaders
and the PS prolog in ACO, so this just implements it for the PS prolog
in LLVM IR.

Using the used component count is not enough. We need to consider
the component mask because any component can be disabled. This might
fix tests.
This removes the component counting from ac_get_fs_input_vgpr_cnt
and determines the component mask where it's needed.

Liveness info can be huge, since with larger shaders it essentially
grows quadratically (linear increase in number of SSA defs *
linear increase in blocks).
Freeing liveness info early helps somewhat mitigate memory usage here.

LLVM 15 is pretty old, and notably not supported by either ANGLE nor
Skia anymore. So let's move up to LLVM 19 using packages provided by
LLVM themselves, apart from PPC and ARMv7 which don't have builds.
The Skia build now requires a bunch of new warning exclusions; hopefully
most of these are no longer needed when we can upgrade Skia shortly.
The ci-deb-repo revision has also been bumped to get us a new version of
xtensor which builds with LLVM 19, and a version of spirv-tools which
also works with LLVM 19.

When building for the dynamic loader used by e.g. Clover, pipe_i915 was
the only target failing to declare a driver descriptor. This becomes an
error with more aggressive linkers.

cat3 instructions read their 3rd src later than their first two srcs.
This was implemented in two different places: once for scheduling and
once for legalization. Extract this logic in a new helper and also add
similar logic for gat/swz there (which the scheduling logic failed to
account for).

Preamble defs were rematerialized at the end of the preamble. However,
when some of the sources were defined inside control flow, this would
lead to these sources not dominating their use. Fix this by finding the
block that is dominated by all sources and inserting the new instruction
there.
Also make sure we only de-duplicate instructions if the new instruction
is dominated by the existing one.

Textures opcodes can't read from the contant registers, however we can
just handle this fine in the native swizzle pass. Others like saturate
for tex instructions) can't happen anyway since we swithed to nir_to_tgsi
long time ago. However, keep the asserts just to be safe.

we no longer allocate registers in NIR, and we try hard to keep the
SSA-like form during the later passes, this is now superfluous.
