    docs/asahi: Add initial driver docs
    
    Emma asked for some docs on how to use wrap for when wrap gets landed.
    This should do :-)

    asahi: Add wrap library
    
    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.

    asahi: Guard against encoder overflows
    
    We don't seem to hit this yet, but it's possible so add an assert to
    rule it out for failing tests.

    asahi: Allocate a larger segment list
    
    This ought to be dynamically allocated but because this is macOS kernel
    UABI only gunk, let's just hack around it...

    asahi: Handle RECT textures as 2D
    
    Rectangle textures are just 2D textures with unnormalized coordinates,
    but we already handle unnormalized coordinates in the sampler state. So
    we just need to alias RECT and 2D.
    
    Fixes GALLIUM_HUD.

    asahi: Sync some more unknown fields
    
    I don't understand these structs well. Good news, though-- Asahi Lina
    confirmed this is all software-defined crap in the macOS UABI.
    Unfortunately, they seem to correspond to physical registers.

    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.
    
    This gets glmark2 -bshadow working.
