nir: add nir_lower_single_sampled::lower_sample_mask_in option
...
GLSL defines gl_SampleMaskIn as :
"a fragment language that indicates the set of samples covered
by the primitive generating the fragment during multisample
rasterization"
when variable rate shading is enabled, a single invocation might cover
multiple samples. The lowering done in nir_lower_single_sampled() does
not account for that case, so add an option to selectively disable it.

This converts a lot of trivial passes. Nice boilerplate deletion. Via Coccinelle
patch (with a small manual fix-up for panfrost where coccinelle got confused by
genxml + ninja clang-format squashed in, and for Zink because my semantic patch

nir: Add a pass for lowering shaders to single-sampled
...
On Intel, we have to do this because we can't ask for the per-sample
barycentrics without setting the per-sample dispatch bit or the GPU will
hang. However, nothing we're doing in this pass is Intel-specific and
it may be a useful optimization for someone else so we may as well make
it a generic NIR pass. This version actually does a bit more than the
current brw_nir_demote_sample_qualifiers() pass as it also handles
pre-nir_lower_io interp_dref_at* as well as a couple system values which
we can easily constant-fold.
