Alyssa Rosenzweig 6e59474ced asahi: Identify partial render pipeline 
Needed if a partial render is incurred from overflowing the parameter
buffer (too much geometry).

Alyssa Rosenzweig 666f307d41 asahi: Add a depth bias structure 
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.

Alyssa Rosenzweig d8541d52d2 asahi: Add XML used for visibility tests 
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.

but it nominally accounts for every byte. So there shouldn't be more

Alyssa Rosenzweig 43f6c08a3b asahi: Handle uncompressed Z32F depth buffers 
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.

Alyssa Rosenzweig 81d22da6de asahi: Fix BIND_PIPELINE sizing and alignment 
Fix a bug in BIND_PIPELINE XML reported by Dougall, which cleans up
a bit of both decoder and driver.

Instead of...

   * 17 bytes BIND_PIPELINE  (17)
   * An unused 8 byte record (25)
   * A set of N 8 byte records (25 + 8 * N)
   * Oops, 1 byte too many! One just disappeared (24 + 8 * N)

It seems to instead be

   * 24 bytes BIND_PIPELINE (24)
   * A set of N 8 byte records (24 + 8 * N)

without the sentinel record. These means the 8 byte records themselves
are shuffled, with the high byte of the pointers split from the low
word, but that's less gross than an off-by-one.

It's still not clear what the last 8 bytes of the BIND_VERTEX_PIPELINE
structure mean, or the last 4 byte of the BIND_FRAGMENT_PIPELINE
structure which seems to be a bit shorter.
