This commit removes anv_format_for_vk_format and adds an anv_get_format
helper. The anv_get_format helper returns the anv_format by-value. Unlike
anv_format_for_vk_format the format returned by anv_get_format is 100%
accurate and includes any tweaks needed for tiled vs. linear.
anv_get_isl_format is now just a wrapper around anv_get_format that picks
off just the isl_format.
Now that we have VkFormat introspection and we've removed everything that
tried to use anv_format for introspection, we no longer need most of what
was in anv_format.
The hardware packets organize kernel pointers and GRF start by slots that
don't map directly to dispatch width. This means that all of the state
setup code has to re-arrange the data from prog_data into these slots.
This logic has been duplicated 4 times in the GL driver and one more time
in the Vulkan driver. Let's just put it all in brw_fs.cpp.

This new macro uses a for loop to create an actual code block in which to
place the macro setup code. One advantage of this is that you syntatically
use braces instead of parentheses. Another is that the code in the block
doesn't even get executed if anv_batch_emit_dwords fails.

Meta currently uses screenspace RECTLIST primitives that lie within
the framebuffer rectangle. Since this behavior shouldn't change in the
future, disable the scissor operation whenever rectlists are used.

The only place we were using this was in meta_blit2d which always creates a
new image anyway so we can just use the image offset.

Previously, we would always emit all of the render targets in the subpass.
This commit changes it so that we compact render targets just like we do
with other resources. Render targets are represented in the surface map by
using a descriptor set index of UINT16_MAX.
There is no API for setting the point size and the shader is always
required to set it. Section 24.4:
"If the value written to PointSize is less than or equal to zero, or
if no value was written to PointSize, results are undefined."
As such, we can just always program PointWidthSource to Vertex. This
simplifies anv_pipeline a bit and avoids trouble when we enable the
pipeline cache and don't have writes_point_size in the prog_data.
This allows us to avoid doing some unneeded work on the meta paths where we
know that the image view will be used for exactly one thing. The meta
paths also sometimes do things that aren't quite valid like setting the
array slice on a 3-D texture and we want to limit the number of paths that
need to be able to sensibly handle the lies.
Rather than keeping separate {vs,hs,ds,gs}_start fields, we now store an
array indexed by the shader stage (MESA_SHADER_*). The 3DSTATE_URB_*
commands are also sequentially numbered. This makes it easy to just
emit them in a loop.
This simplifies the code a little, and also will make it easier to add
more credible HS and DS code later.
We can't use a global descriptor pool like we were because it's not
thread-safe. For now, we'll allocate them on-the-fly and that should work
fine. At some point in the future, we could do something where we
stack-allocate them or allocate them out of one of the state streams.
Descriptor pools are an optimization that lets applications allocate
descriptor sets through an externally synchronized object (that is,
unlocked). In our case it's also plugging a memory leak, since we
didn't track all allocated sets and failed to free them in
vkResetDescriptorPool() and vkDestroyDescriptorPool().
