It has been incorrectly interpreting its SkColor as sRGB all the time. Now, we plumb through the destintation color space and some scratch space, letting it decide how to interpret its SkColor later when it knows about the dst color space. The scratch space is blitter scoped, which lets this be thread safe (this is much like SkShader::Context).
This only corrects the gamma transformation for now. I've kept my previous TODO about gamut transformation. Everything assumes sRGB gamut for now.
Shaders will get the same treatement in this pipeline.

This breaks the color filter down into a couple logical steps:
- go to unpremul
- apply the 4x5 matrix
- clamp to [0,1]
- go to premul
Because we already have handy premul clamp stages, we swap the order of clamp and premul. This is lossless.
While adding our stages to the pipeline, we analyze the matrix to see if we can skip any steps:
- we can skip unpremul if the shader is opaque (alphas are all 1 ~~~> we're already unpremul);
- we can skip the premul back if the color filter always produces opaque (here, are the inputs opaque and do we keep them that way, but we could also check for an explicit 0 0 0 0 1 alpha row);
- we can skip the clamp_0 if the matrix can never produce a value less than 0;
- we can skip the clamp_1 if the matrix can never produce a value greater than 1.
The only thing that should seem missing is per-pixel alpha checks. We don't do those here, but instead make up for it by operating on 4-8 pixels at a time.
We don't split the 4x5 matrix into a 4x4 and 1x4 translate. We could, but when we have FMA (new x86, all ARMv8) we might as well work the translate for free into the FMAs.
This makes gm/fadefilter.cpp draw differently in sRGB and F16 modes, bringing them in line with the GPU sRGB and GPU f16 configs. It's unclear to me what was wrong with the old CPU implementation.

Our internal definition is (and will continue to be) that anything with
a color space is gamma correct. F16 is irrelevant (whether or not we
choose to support untagged F16). This makes these helpers less than
helpful, and lets us remove them from (public) API.
API change is just removal (of unused functions).

The main idea here is to simplify, mainly to reduce the number of SkRasterPipeline objects the blitter holds.
- Use SkBlendMode instead of SkXfermode, just store SkBlendMode.
- Fuse the shader and color filter together into one SkRasterPipeline
during blitter creation.
- I noticed all calls to append_load_d() and append_store() now have the same ctx argument, so I folded that through.
I'll be following up with more of this sort of refactoring... I think I can fold everything into a single SkRasterPipeline during blitter creation now, but I'll want to make sure I've got my ducks in a row for how that works with pipeline strength reduction (like skipping dst loads when drawing in Src mode).

Many places that construct one are explicitly specifying opaque white or
transparent black, which we can assume (based on the semantics of the
operation) should remain (0,0,0,0) or (1,1,1,1), so that's simple.
In other cases, we convert our source color to destination space.
One wrinkle is tht SkColorFilter now needs to know the destination color
space, due to SkModeColorFilter.

return sk_sp (or any type that intelligently manages its own

Previous factories are still around, assuming
SK_SUPPORT_LEGACY_COLOR_SPACE_FACTORIES is defined. Enable that
define for Android, etc.

Some classes directly call global operator new to reserve space in
addition to the space the class will occupy. These clases must be
deleted with the unsized global operator new. If a build is configured
such that sized global operator new is called from a delete expression,
this must be overridden by such classes.
