b5a4843c1f GPU: Purify ConvertViewportAndScissor(). 
This makes it harder to misuse.  See #15856.

462972f7ea Add option to redirect blue to alpha if 565 mode is rendered and mask is 0x0FFFFF. 
This is used by several games to render to the alpha channel of RGBA4444
images, which cannot normally be done directly on the PSP.

Can be used as a far more efficient replacement for
ReinterpretFramebuffers/ShaderColorBitmask

32df78a2cc Make the existing ReinterpretFramebuffers/ShaderColorBitmask path work for Split/Second 
It took writing and debugging #15500 for me to understand what the issue with the old path was..

Much simpler alternative to #15500, or we could merge both but disable Split/Second
for this one. Needs some benchmarks I guess...

45308a16c0 Vulkan is strict about scissor rect, so let's clamp centrally. 
Better than spreading the logic all over.

Fixes #15207

3d289594f9 ShaderBlend and FramebufferRead are separate concepts. Reflect that in naming. 
The former has forms that don't need to read the framebuffer.

This exposes that some logic is wrong...

e6dfb55d3d Optimize value conversion in (unused) depth readback. 
This also exposes factors we can feed into shaders to do the conversion
on the GPU.

b955ec70c9 GPU: Correct depth clamp range in range cull. 
It was just wrong before, causing wrong culling when using a non-standard
viewport scale/center for depth.

Fixes #11701, fixes #11781.

5932cbabc3 GPU: Avoid stencil emulation if possible. 
This reduces use of replaceAlpha, and reduces use of more complicated
blend states.  This simplifies fragment shaders a little.

5ad948df73 Vulkan: Avoid discard when we can blend. 
Where possible, replace alpha and color testing with a zero alpha value.

This allows early fragment tests more often, which may help #11227.  It
may also generally help performance on PowerVR devices.

529abd7db4 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.

c31a8f860b Adjust stencil ops for 5551 and 565 buffers. 
This attempts to better approximate the operations that actually happen,
where possible.  Expected to help #5278.
