This turns the early pass into a late pass, which is important because it
depends on the shader key and therefore should be called by the driver instead
of the compiler preprocessing. It's also simpler this way.
The shader key work is waiting for review in another merge request. In the mean
time, this patch will let us run blend lowering early for blend shaders on
Midgard.

This is a form of lowered I/O, it needs I/O semantics so we can know the
location to store to instead of passing via a sideband.
Over in !20906, we will use the BASE to lower blend shader with multisampling in
NIR instead of passing the number of samples and framebuffer format along a
sideband to the Midgard compiler. That's not needed for this series (this patch
was cherry-picked to avoid regressions in the lower_blend changes) but it's good
to model the full form of the I/O lowered intrinsic here.

This switches us over to Mesa's code style [1], normalizing us within the tree.
The results aren't perfect, but they bring us a hell of a lot closer to the rest
of the tree. Panfrost doesn't feel so foreign relative to Mesa with this, which
I think (in retrospect after a bunch of years of being "different") is the right
call.
I skipped PanVK because that's paused right now.

Bifrost onwards handle this in hardware, and the Midgard lowering isn't
too terrible. Enable the format, otherwise desktop GL apps such as
Hacknet try to render to the format and get an incomplete framebuffer.
Cc stable because apparently we've been advertising this format
unintentionally as a result of some other interaction? Unclear how
Hacknet is hitting this, maybe it's an app bug. Shrug, it's not a big
deal regardless.
Additionally, we need to restrict texturing from 32-bit normalized due
to a restriction added with the v7 pixel format fiasco. That means
restricting rendering to 32-bit normalized on v7 onwards.

There is a single quirk it cares about. Pass just that, so the relevant quirk

This was made way more complicated than it needs to be for a Midgard-only pass.
The only caller doesn't care about the class, only if it's native or not.
Simplify it appropriately.

These "quirks" are common for Midgard, yet are only consumed by
pan_lower_framebuffer -- a Midgard-only pass. So the quirks should be removed
and inlined into their users. Thid removes MIDGARD_QUIRKS altogether.

The output swizzle defined in the render-target descriptor is ignored
when the format is RAW. In that case, we have to swap the components
when lowering FB stores/loads if we want to get the right color.
