softgpu: Simply 5551 blending fast path.
...
Since it only supports multiply and add, let's just stick with that.

softpu: Refactor out 5551 fast path checks.
...
They were duplicated, and better to organize them according to state.

softgpu: Avoid fast path in another wrong case.
...
Seen in Kurohyo. Missed that the alpha blend check essentially means only
standard blending can work.

softgpu: Narrow blend check for fast path further.
...
See #15756 , frame was largely black because of a full screen blend
rectangle intended to brighten the screen slighty (I assume.)

softgpu: Simplify vertex range culling.
...
The previous logic was harder to understand and easier to get wrong.
Just drop them when clipping the primitive.

softgpu: Remove mostly unused screen offset state.

This is now already cleaned up from coords, so no need to cache it.

Seen in a dump from Infected, improves FPS ~25% there.

softgpu: Restrict sprite fast path to throughmode.
...
Its UV checks already should have generally, but let's be safe. It
doesn't validate state like fog, etc.

softgpu: Clamp/wrap textures at 512 pixels.
...
A texture larger than 512 is "valid", but simply wraps/clamps at 512.
Importantly, the texture coords are still calculated at the specified
size, which can be up to 32768.

These are just corners, we don't know if they're top or not at this point.

softgpu: Avoid over-aggressive rect conversion.
...
The TL and BR have to match between UVs and pos, not enough for UV to be
in order. This was causing an artifact on Chains of Olympus' title.

softgpu: Correct texture check in fastpath.
...
This is the no textures option, so we shouldn't check sampler state at
all. Presumably this was failing and reading uninitialized data...

softgpu: Avoid rect fast path with subpixel offset.

It doesn't handle it right, see #15876 . We still handle these with
DrawRectangle(), which gets it right.

This simplifies tighter calculations, and reduces the common magnitudes
we'll be dealing with.
