pan/mdg: Use special NIR ops for trig scaling
...
Otherwise the lowering is fundamentally unsound due to incorrect constant
folding, even though it worked by chance with the old pass ordering. We're about
to change slightly the way we handle fsin/fcos, which was enough to trigger this
unsoundness.
shader-db results are mostly a toss-up.

Image coordinates are 16-bit long in midgard, so we must lower them
before emitting image opcodes.

panfrost: Move non-Gallium files outside of Gallium

In preparation for a Panfrost-based non-Gallium driver (maybe
Vulkan...?), hoist everything except for the Gallium driver into a
shared src/panfrost. Practically, that means the compilers, the headers,
and pandecode.
