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.]

All current drivers reports supporting this cap, let's just assume
it's always supported.
It seems better to lower this in the drivers, like we already do for
etnaviv, panfrost and zink...

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.

This extension adds new NONE attachment load / store operations,
which are identical to the DONT_CARE variants with the difference
that DONT_CARE doesn't ensure that the original contents of the
memory within the render area are preserved and these new versions
do (with some caveats).
Our implementation was not destroying data with DONT_CARE anyway
so we already support the new semantics. Our implementation is
such that we don't need to do anything specific with the new
operations and the current behavior will do what is expected.
We pass all the tests under:
dEQP-VK.renderpass*.load_store_op_none.*

This is a trivial implementation where we just insert a UBO descriptor
pointing to the actual data and then treat it as a normal UBO everywhere
else. In theory an indirect CP_LOAD_STATE would be more efficient than
ldc.k to preload inline uniform blocks to constants. However we will
always need the UBO descriptor anyway, even if we lower the limits
enough to always be able to preload them, because with variable pointers
we may have a pointer that could be to either an inline uniform block or
regular uniform block. So, using an indirect CP_LOAD_STATE should be an
optimization on top of this.

OpenGL 3.0 requires RGTC support, and until we have emulation in place,
we should document that requirement.
