2868495cf8 softgpu: Use SSE for lighting ceil if available.
Tiny optimization, helps only a little.

b5206df04f softgpu: Calc worldnormal a bit less often.
This is clearer anyway.

f1b5cbf993 softgpu: Fix lighting with 0 exp.
Broken in #15317.  Fixes Kratos scene demo.

a7b7bf7826 Global: Set many read-only params as const.
This makes what they do and which args to use clearer, if nothing else.

8a6e8066bf softgpu: Store vertex colors as packed RGBA8.
No need to keep it expanded at 4x the space for both colors.

2479d52202 Global: Reduce includes of common headers.
In many places, string, map, or Common.h were included but not needed.

76f9103e97 softgpu: Add a table and initial dirty flags.
Not actually using the dirty flags to skip state, but have moved to
Execute_* functions and everything else like other graphics backends.

7218fbbe97 softgpu: Guide more SSE light factor handling.
Missed these others in computed state.  Helps mostly to do this inside
Process().

fcc3b7684e softgpu: Use SSE in lighting param computation.
The compiler couldn't figure this out.  Halves time in this func.

2797e035df softgpu: Precompute lighting parameters.
In many cases, games use lighting just for diffuse or something, this
helps skip what's not needed too.  Good improvement in a scene from a
Naruto game.

d6a8cb2a0e softgpu: Stop storing normal/worldnormal/worldpos.
This is only needed for lighting, which is applied right away.

This improves perf just simply from less data being copied.

ce8a49b1c1 softgpu: Retain floats in diffuse/specular.
This seems to be a bit more accurate.  Color blending seems correct now,
but the factors and especially pow results are off.

Also, normalize normal to 0, 0, 1, which seems to match results better.

cba2374abd softgpu: Separate calculation of S/T.
We could probably reuse, but we're not right now and it complicates the
logic.

Gives about a 2% improvement in many places.

2f63f9999d GPU: Normalize 0 to 1 always in software lighting.
See #14167.  This seems to be consistent.

4a0109d273 GPU: Treat negative light exp same as 0.
Based on #12507 and some tests, seems like negative exponents are also
fixed to a 1.0f result.

4816bfc1a6 GPU: Skip specular on negative diffuse factor.
This is correct per hardware tests, see #8403.  Note that the PS3 emulator
running PSP HD remasters does not correctly handle this, and applies
specular for negative diffuse factor.

6e46d6c0f9 GPU: Correct powered diffuse with exp=0.
Just to ensure negative factors are handled too, as they are on hardware.

Avoid using Length() when Length2() is enough, simplify some things.

Using floats simplifies things and also makes it faster.

25bc394284 Ignore the material update flag w/o vertex color.
Instead of using materialambient for all of them.

Fixes #3918, and seems to match tests with 3dstudio.
