Alyssa Rosenzweig 19ded1e121 panfrost: Use packs for fragment properties
A bit more complicated, since there are dependencies on other state (for
early-z and discard handling). We separate this cleanly to help defer
packing later.

Alyssa Rosenzweig 87c59514e9 panfrost: XMLify Midgard properties
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.

Alyssa Rosenzweig 58ae50f1b1 panfrost: Clean up blend shader errata handling
The cases of SFBD blend shaders (which work normally) and MFBD blend
shaders (which need a bizarre errata workaround) are distinct. Let's
seperate them to make each a bit clearer.

Since this field is repurposed on Bifrost, this should fix bugs there
too (although blend shaders on Bifrost are currently todo).

Alyssa Rosenzweig 9a2df304ed panfrost: Specialize compute vs frag shader init
In exchange for a bit of code duplication, we can streamline both
routines. A huge amount of the descriptor is unused for non-fragment
shaders, and even some of the parts that are used appear to have varying
meanings. Given we want to emit the descriptors atomically, this seems
like a reasonable tradeoff.

Rob Clark 1fa43a4a8e freedreno: handle case of shadowing current render target
If you have a sequence where there is a single buffer associated with
the current render target, and then you end up shadowing it on the 3d
pipe (u_blitter), because of how we swap the new shadow and rsc before
the back-blit, you could end up confusing things into thinking that
the blitters framebuffer state is the same as the current framebuffer
state.

Re-organizing the sequence to swap after the blit is complicated when
also having to deal with CPU memcpy blit path, and the batch/rsc
accounting.  So instead just detect this case and flush if we need to.

This fixes the Mesa code to use a valid metric set ID (1 could work
