Correct clamped depth range from [0, 65535].
...
This changes a few things:
* All backends clamp the depth range and keep it positive.
* The depth rounding uniform is now properly dirtied.
* Projection is updated to translate and scale appropriately.
* Depth rounding is halved on OpenGL to account for [-1, 1] range.
Fixes Phantasy Star Portable 2 without the need for a game-specific hack.

This attempts to better approximate the operations that actually happen,
where possible. Expected to help #5278 .

Optimize inverse blending modes, where possible.
...
Also, take advantage of cases where we can double src and src.a in the
shader, which can in some cases get us closer to accurate.
