All PS lowering that changes, adds, or removes system values based on
the shader key is done first, which is done in ac_nir_lower_ps_early and
other passes, so now we just need to gather them.
This should improve performance for ACO due to fewer VGPRs needed
for optimized shader variants of PS.

We need to do this before we gather shader_info because lowering indirect
indexing can trigger more code elimination.
The opts_not_run parameter is removed because it was only needed for array
temps.

This removes duplicated gathering from 3 places for shader variants,
and adds it where it should be, which is before late optimizations and
late lowering passes, which is where we want it for the radeonsi linker.

It will be done in a different place later, but for now, we need to get
it out of si_update_shader_binary_info because the function will be
removed and PS input gathering will be moved, which will be quite
complicated, but it's needed for having a linker in radeonsi.

This is a prerequisite for linking merged shaders.
At the beginning of get_nir_shader (renamed to get_nir_shaders), we get
both shaders that are going to be merged, and then we optimize them together
and pass them to LLVM or ACO-specific code as struct si_linked_shaders.
The code setting uses_instance_id is moved because the previous place
doesn't work with this new organization.

This splits shader variant compilation into the following stages:
* get_input_nir
* run_pre_link_optimization_passes
(not implemented yet: run linking optimizations here)
(not implemented yet: gather shader_info here)
* run_late_optimization_and_lowering_passes
This order is important when we start adding linking optimizations for
shader variants and start getting shader_info from shader variants instead
of input NIR.

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.

We don't actually need this anymore. We were previously using it to find
ccache, but Meson will do this for us. Now that we pass
-Wl,--fatal-warnings, we don't need to pass -Werror to the link stage
either.
This removes two shell execs, one subshell, and one call to each of grep
