There's no GL_NV_gpu_shader4 extension, and the TEX opcode is defined in
NV_gpu_program4. Correct the mistake.

9b55f1c12b docs: upgrade some links to https 
We're in 2022 now, and HTTPS is available in a lot more places in the
past. Let's upgrade some links, to protect the privacy of our readers.

The links that are left either don't support HTTPS, or are simply dead
and needs to be updated anyway. That's besides the scope of this
merge-request, so I'm leaving that for someone else.

5525d0b196 docs: use inline-code instead of default role 
A single backtick escaped string in Sphinx refers to the "default role"
which is vague, and in practice ends up producing the HTML cite-element.
That's almost certainly not what these uses wanted.

A bunch of these would probably be better served using appropriate roles
instead of inline-code markup, but this is almost certainly what was
meant here instead. Let's not let perfect be the enemy of good here, and
just do what was intended. Using the right roles everywhere is a big
task.

I usually don't do changes like these to the relnotes, but in this case
there were a *single* article that had these mistakes. I assume that was
an early bug in the script that generateg the relnotes. Let's patch it,
so we don't get misrendering if we change the default-role.

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.
