e749f67f89 mesa,gallium: Make point coord origin a CAP 
When lower_wpos_pntc is used, the state tracker inserts code to
transform gl_PointCoord.y according to a uniform, to account for
API-requested point coordinate origin and framebuffer orientation. With
the transformation, driver-supplied point coordinates are expected to
have an upper left origin.

If the hardware point coordinate supports (only) a lower left origin,
the backend has to use lower_wpos_pntc and then lower *again* to flip
back. This ends up transforming twice, which is wasteful:

   a = load point coord Y with lower left origin
   a' = 1.0 - a
   a'' = uniform_transform(a')

However, lower_wpos_pntc is quite capable of transforming for a lower
left origin too, it just needs to flip the transformation. Add a CAP
specifying the point coordinate origin convention, rather than assuming
upper-left. This simplifies the Asahi code greatly.

8c4b88ee48 gallium+glsl: Remove EmitNoSat/PIPE_CAP_VERTEX_SHADER_SATURATE 
The drivers not setting it were:

- nv30, which gets lowering using NIR's lower_fsat flag.
- r300, which gets lowering using NIR's lower_fsat flag.
- a2xx, which has was getting it optimized back to fsat anyway.

This drops the check for the cap from gallium nine.  While nine does have
a non-nir path, I think it's safe to assume that if you have SM3
texturing, you can do fsat.

before GL_EXT_depth_clamp introduced the ability for hardware drivers to
expose the feature on GLES.  Now that we have that, the desktop-GL-capable
HW that virgl cares about can expose desktop GL even on its GLES renderer
on the host without this emulation.  I don't think anyone particularly
cares about hitting higher GL versions on actually-core-GLES hosts with

currently, the only known limitations are:

8297d243fb gallium: add PIPE_CAP_VERTEX_ATTRIB_ELEMENT_ALIGNED_ONLY 
vulkan requires that vertex attribute access be aligned to the size of
a component for the attribute, but GL has no such requirements

the existing alignment caps are unnecessarily restrictive for applying
this limitation, so this cap now pre-calculates the masks for elements
and vertex buffers in vbuf to enable rewriting misaligned buffers
