Optimize color tests against zero.

They seem to be somewhat common. Speeds up Tales of Phantasia X a bit.

GLES: Merge the two ShaderID classes as they are identical.
...
I don't expect the number of bits required to grow or shrink massively for either type of shader in this backend.

Premultiply for doubled alpha blending if possible.
...
This makes the effect more accurate where the values were being clamped
before. Some obscure methods of blending may be slower.

Apply unsupported blending modes in the shader.
...
This handles unsupported fixed color combinations, alpha doubling, etc.
Where possible, tries to avoid it - it means using a blit (without the
framebuffer fetch extension), which can slow things down a lot with tons
of drawcalls.

Avoid forcing nearest/disabling linear if possible.

If we know that the test is trivially true, we don't need to worry about
the test. May help #4405 .

Replace alpha when blend mode allows it.

Some games are using fixed/fixed blending modes which work in our favor.

Switch to "GPL 2.0 or later" for various reasons. I wrote most of the code I imported from Dolphin (which is GPL2-but-not-later), so it should be OK.
