4c7a44413a mesa,gallium: Revert "Make point coord origin a CAP" 
This reverts commit e749f67f89, which added a CAP
to support drivers that can only do upside-down point coordinates. That was
added specifically for Asahi, since Metal's point coordinate convention is
opposite Mesa's. Since then, additional reverse-engineering aided by the PowerVR
headers led me to the bit doing the flip in hardware, so Asahi does not use the
CAP since baadc1ec13 ("asahi: Don't use lower_wpos_pntc"). Garbage collect it.

[If it's needed for future hardware, we can revive it. But the plan is Vulkan
anyway.]

55f6a2bb51 gallium: normalized_coords -> unnormalized_coords 
A lot of code zero-initializes pipe_sampler_state, and sets the states
the non-zero fields manually. This means that normalized_coords is the
"default" setting.

However, setting normalized_coords to true isn't allways allowed, and
we'd need to check PIPE_CAP_TEXRECT first. So it's not really the ideal
default here. There's recently been found quite a bit of bugs in this
area, where the state-tracker didn't properly lower texrects.

Let's switch this around to avoid more bugs like this in the future.

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.

- 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.
