When using nir_lower_interpolation, we need to propagate the IO
semantics from the load_interpolated_input to the new
load_fs_input_interp_deltas intrinsics. nir_lower_io assumes
they will be filled out.
This fixes assertions in most tests on iris since commit
01ab308edc, where nir_lower_io
started reading this field.

These special OPAQUE packs use packed structs in the struct template,
instead of struct templates. The use case is packing nested structs
out-of-band, to fit into the CSO model.
A more conventional GenXML solution would be an overlapping uint, but
this breaks our assumptions about struct packing which are otherwise
correct, so this seemed less intrusive than risk disrupting the main
pack routines.

This contains a bit of everything, so just XML for this commit. The rest
of the series will be slowly moving over to this representation.
The one noteworthy addition is the rename of "No MSAA" to
"Single-sampled lines". This came about due to a buggy branch that
forgot to set this bit. Ths worked, with the caveat of the following
tests failing with a single-sampled framebuffer:
dEQP-GLES2.functional.rasterization.interpolation.basic.line_loop_wide
dEQP-GLES2.functional.rasterization.interpolation.basic.line_strip_wide
dEQP-GLES2.functional.rasterization.interpolation.basic.lines_wide
dEQP-GLES2.functional.rasterization.interpolation.projected.line_loop_wide
dEQP-GLES2.functional.rasterization.interpolation.projected.line_strip_wide
dEQP-GLES2.functional.rasterization.interpolation.projected.lines_wide
dEQP-GLES2.functional.rasterization.primitives.line_loop
dEQP-GLES2.functional.rasterization.primitives.line_loop_wide
dEQP-GLES2.functional.rasterization.primitives.line_strip
dEQP-GLES2.functional.rasterization.primitives.line_strip_wide
dEQP-GLES2.functional.rasterization.primitives.lines
dEQP-GLES2.functional.rasterization.primitives.lines_wide
That is, this bit controls the behaviour of line rasterization with
multisampling. This is required to implement the divergent behaviours
described in the OpenGL ES 3.2 specification sections 13.6.1 ("Basic
Line Segment Rasterization") and 13.6.4 ("Line Multisample
Rasterization"), where setting this bit corresponds to the former
(single-sampled) behaviour.

For non-fragment shaders, we can just use the preuploaded BO as-is and
do no packing/copying at draw-time. Fragment shaders are still a bit of
an edge case, in having rasterizer/zsa/blend state in the same

fragment-only.

This isn't as clean as vertex shaders, since some of this state is only
known at draw-time (e.g. some reasons we might disable early-Z). But we
can still pack as much as we can ahead-of-time and then OR together
what's left at draw-time.

In a long journey to a full XML representation of mali_shader_meta,
let's start with the fourth word, containing some shader properties.
This is a translation from panfrost-job.h, with the exception of
widening the uniform buffer count field [1]
The other noteworthy change is combining the unknown 0x20 flag with the
WRITES_Z flag to form a 2-bit depth source. This papers over the fact
that the blob zeroes this field for non-fragment shaders. Given the
proximity, this is a reasonable guess and avoids an ugly "is_fragment"
bit.
[1] Justified by the increased limit advertised by the Vulkan blob
