The shader depal CLUT8 mode now handles 565, 5551 and 4444 framebuffers
(the format goes in the depal format bits, which this mode didn't fill
before), rebuilding the 16-bit pixel and taking its low or high byte.
This replaces SOCOMClut8Replacement, which assumed the high byte.
- The GE samples a pixel at its corner, the GPU at its center. With u
stepping two bytes per pixel (SOCOM and Bend's games use u = 1 + 2x)
that's a whole byte, so the shader steps back to the corner.
- The CLUT index shift, mask and start are applied, as in the other
depal modes.
- The self-render copy region counted CLUT8's U in pixels, not bytes.
SOCOM, Star Wars: The Force Unleashed and the NPJG90068 dumps improve a
lot. Syphon Filter and Resistance: Retribution now read the right bytes,
which exposes a 16-bit precision difference in their bright pass.

The game reduces the scene to 8x8 on the GPU, block transfers that into RAM,
and the CPU sets its brightness adaptation from it. With BlockTransferAllowCreateFB
the copy went into a GPU-side buffer instead, the CPU read stale RAM, and the
game kept getting darker on the hardware backends (#15914).
New compat flag BlockTransferReadbackSmall: transfers of up to 64 pixels into
RAM are still read back, a frame late, so it doesn't stall. Brightness from
the issue's savestate now follows the software renderer's (72 vs 84 at 6 s,
84 vs 95 at 20 s, from 25 and falling), at the same speed as before.

Partial red, green and blue write masks now always go through the shader with
a framebuffer read. Across the frame dump set this only improves games outside
the old list (Split/Second, Ultimate Ghosts 'n Goblins, older DiRT 2 and OutRun
dumps without a game ID). Partial alpha masks keep the old heuristic: alpha is
the stencil, with its own write mask, and taking the shader path for them made
Pro Yakyu Spirits and Gangs of London worse.

There are a few games that seem to rely on performance problems or
timing quirks to hold the correct pace when playing sceMpeg - have not
been able to nail down any other timing mechanism.
This adds a timing enforcement function.

CmdLine used std::stoi/std::stod and Compatibility used stoi/stof, all of which
throw on junk with nothing catching them. 'PPSSPPHeadless --timeout=abc' aborted
the process, and so did a bad value in a [PostShaderSetting]-style compat section -
at startup, with no diagnostic. Parse with sscanf and report it: CmdLine already
has the pattern for this in its Bool case, and Config.cpp's ini reads were fixed
the same way earlier. A bad compat.ini entry now warns and keeps the default.
Fixes#21776
Since only two games are known to need the cull-after-clip behavior
(previously known as inversion), we flag those and avoid unnecessary
soft clipping.
I had hoped to find a dynamic check that would work, but haven't managed
to figure out a good one yet.
This will improve performance a little bit in some other games since we
can avoid clipping in software at all in many cases.
This reverts to the old behavior before we started parsing mpeg headers,
that is, in 558b462 which is part of #8867.
LunaMoo has this under "HackFixVideo" in his build.
See #8991. This doesn't really "fix" that, but works around it.
* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
