Unify ICC support for gray jpegs and gray pngs

(1) Parse ICC gray profiles into RGB SkColorSpace objects.  This is
    easy - "gray transfer fn + white point" is subset of "RGB transfer fns
    + matrix".  This makes it easier/possible for the drawing code to reason
    about color spaces attached to kGray buffers.
(2) Allow gray images to be tagged with gray ICCs OR rgb ICCs.  ICC gray
    forces to designer to use "D50 gray".  It is not uncommon to see gray
    images with RGB profiles - and this actually allows the designer to
    choose more kinds of gray (ex: sRGB gray).
(3) Make SkJpegCodec support gray images with RGB ICCs.
(4) Make SkPngCodec support gray images with Gray ICCs.
(5) Delete gray from SkColorSpace_A2B - we no longer create these objects
    for gray profiles.

GrTessellator: fix artifact with exactly-1-px-wide edges.

When path features are exactly a pixel wide, the extruded inner edges
can become collinear and then be removed, since their winding is
zero. We need these edges to be preserved through triangulation,
otherwise opaque portions of the geometry can become transparent.

Since the simplify() pass can handle zero-winding edges just fine, the
the fix is to simply not remove them.

In addition, this changes refactors out disconnect() from all the calls
to remove_edge_above()/remove_edge_below(). It also renames the remaining
function erase_edge() (since it's now unconditional).

Add readPixels() tests for generator backed images

Good news:
Everything seems to work as it is supposed to.  That's why this
CL is just tests.

Bad news:
Picture is a bit strange in that the caching behavior may affect
how the output looks.  Ex: If we choose to cache, we will first
draw into the picture's colorSpace and then convert that to the
dstColorSpace.  If we choose not to cache, we will draw directly
into the dstColorSpace.
And then untagged pictures seem like they really shouldn't work
very well...  We are caching a legacy draw and then drawing that
into the dstColorSpace?  Maybe this isn't the most critical
thing to think about right now though, given Florin's work.

Remaining TODOs:
Color space support for gpu-backed images.
I still plan to clarify conversions that are allowed vs. not
allowed and share that code between all SkImages.

Add Gray8 pixel config

This is still just linear (non-sRGB), but adding sRGB will
be the next step. I've verified that this is really making
R8 textures when uploading Gray8 bitmaps. Tests pass, and
the all_bitmap_configs GM still renders correctly (unlike
when we just mapped Gray8 to Alpha8).

This adds another pixel config, which could grow our cache
footprint, but the benefits of not using 4bpp for 1bpp data
should outweigh that?

Re-land of https://skia-review.googlesource.com/c/6817/,

SkSplicer: no need to set_k() manually.

set_k() is simulating the effect of loading a pointer constant into the register used to pass the 4th function argument.  An easier way to do this is to pass that pointer constant as the 4th function argument... duh.

SkSplicer

I think I may have cracked the compile-ahead-of-time-splice-at-runtime nut.

This compiles stages ahead of time using clang, then splices them together at runtime.  This means the stages can be written in simple C++, with some mild restrictions.

This performs identically to our Xbyak experiment, and already supports more stages.  As written this stands alone from SkRasterPipeline_opts.h, but I'm fairly confident that the bulk (the STAGE implementations) can ultimately be shared.

As of PS 25 or so, this also supports all the stages used by bench/SkRasterPipelineBench.cpp:

    SkRasterPipeline_…
    400  …f16_compile 1x  …f16_run 1.38x  …srgb_compile 1.89x  …srgb_run 2.21x

That is, ~30% faster than baseline for f16, ~15% faster for sRGB.
