We don't need to pass the indentation level explicitly if we use
pandecode_log() instead of fprintf(). This helps keeping a consistent
indentation across descriptors.
While at it, let's rework those macros to allow creating titles from
a format string.

Panfrost descriptors are big and are usually built from a combination of
sub-descriptors. On top of that, layout of sub-descriptors might vary
depending on the architecture version. Since unions are not really an
option (too complex), here is a thin abstraction layer allowing us to
manipulate aggregates in their packed format. Each aggregate is formed
of one or more sections that are meant to be packed/unpacked/printed
separately. Section overlapping is allowed to facilitate handling of
descriptor variants.

Mali has a special 5:3 encoding representing a subset of the natural
numbers, of the form:
a * (2^b)
for a odd and b natural/zero. It is used for padding out instance sizes,
as well as in attribute records so it's worth representing as a native
type as opposed to having manual packs/unpacks in various places.

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.

There's a lot of code here since the meaning of this field changes
depending on shader state. The good news is that our careful handling
allows preload registers to be decoded now, which pandecode could not
previously do. Likewise, the cmdstream code to emit this is now much
more obvious.

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
(maxDescriptorSetUniformBuffers on
https://vulkan.gpuinfo.org/displayreport.php?id=5602#limits). Not
actually supported in Panfrost right now.
