Add a library that wraps the key IOKit entrypoints used in the macOS
UABI for AGX. Our wrapped routines print information about the kernel
calls made and dump work submitted to the GPU using agxdecode. This code
has two major use cases:
1. Debugging Mesa, particularly around the undocumented macOS
user-kernel interface. Logs from Mesa may compared to Metal to check
that the UABI is being used correcrly.
2. Reverse-engineering the hardware, using this as glue to get at the
"interesting" GPU memory.

Validate all the new expectations and print all the fields. This should
make differences between the drivers obvious, I hope.

This should clarify a few things I didn't get independently
investigating the interface. Of coruse, I got other pieces... the sum of
the parts is better :-)

This is simple and corresponds directly to the Metal inputs. However,
the alignment is a bit tricky, so let's add formal XML for it.

...used internally with visibility tests, together with a weird
vertex/compute-like shader used to zero the visibility buffer.

Aka occlusion queries. There is an annoying limitation in the hardware
(reflected in Metal) that only a single buffer may be bound per render
pass, with the per-draw settings merely specifying an offset.

This adds the remaining XML. I don't know how much of this is correct,
but it nominally accounts for every byte. So there shouldn't be more
surprises in the command buffer after this.

Context switching is so broken. Just trying to get closer. Adding some
XML here to see if we're missing something else obvious.

This uses a subset of the depth/stencil infrastructure we built out to
support writing back tiled, uncompressed Z32F depth buffers to memory.
Texturing from this format is already supported.
This gets glmark2 -bshadow working.

C++ requires explicit casts from integers to enums. Fixes errors like
the following when trying to use Asahi GenXML from a GTest unit test.
src/asahi/lib/agx_pack.h:554:23: error: assigning to 'enum agx_channels' from incompatible type 'uint64_t' (aka 'unsigned long long')

As far as I can tell, these *must* be tiled. Other than that, the
implementation is completely routine. Passes
