Also use GrColorTypes wherever possible.
As a consequence, some cases now go through GrSurfaceContext rather
than SkSurface (because it uses GrColorType and allows kUnpremul).
Both changes make it easier to add testing for GL_LUMINANCE8_ALPHA8,
which is required to update Flutter on iOS/GL to use new YUVA
texture image api.

Previously, multiple inliner passes in a row would each apply a
separate name mangling to variable names, so names like "_25_14_3_1_pos"
were not uncommon. This change demangles the name before re-mangling it,
so we would have just "_25_pos" instead.
It's not important, but it makes things easier to read.

Key design points...
A) Take care to not commit too much to Half's range or precision.
In particular, don't offer operations whose result might not
be representable in Half. E.g., shy away from Half divide,
not just because we might not be able to do a native divide,
but even more so because division produces results that might
not fit in Half, ±inf or NaN.
B) No native Half loads, stores, uniforms or splats,
instead converting from I32 or F32. This keeps the entire
front-end (user code, Builder, etc.) specified in terms of precise
format and oblivious to the various backends' representations of
Half. Native Half splats would be less trouble than uniforms I
think, and uniforms less trouble than loads and stores, but still
enough a pain that we're better of deferring any of that for now.
(Explicit fp16 uniforms do make sense to me though.)
C) Keep the current F32-based Color and all the effect virtuals
that use it around, introducing parallel Half-based HalfColors
and entry points for those. The key cool idea here is to have
the default entry points for F32/Color and Half/HalfColor call
each other, so that any given effect can implement one, the other,
or both and always be compatble with however it's called.
This is mostly about incremental rollout, but I suspect we'll
have areas that stick to F32 forever. (Think the IEEE 754 32-bit
float specific bit hacks we used for approx_log/approx_exp.)
D) (not done yet) allow implicit Half->F32 conversion, but not
the other way around of course. This makes it easier to lean
on the body of F32 routines we already have, and again mostly
helps enable incremental rollout.

This is a new base class for GrSurfaceDrawContext. It allows any
alpha-type but is restricted to non-blending fills of irects using FPs,
clears,and discards.

The GLSL backdoor for tessellation shaders is only experimental at
this point. In order to enable the tessellation path renderer, we need
to turn off HW tessellation and let it use the indirect draw modes.

This mostly undoes commit 2777cd37 "Have SkWuffsCodec use two Wuffs
decoders", also known as
https://skia-review.googlesource.com/c/skia/+/250937
Using two Wuffs decoders is more complicated, but was necessary to allow
getFrameCount() to update when part-way through an incremental decode
while more data comes in. Updating that count matches an existing
Chromium test (TestResumePartialDecodeAfterClearFrameBufferCache).
On further discussion (crbug.com/1132828), that behavior is unnecessary
(and that Chromium test will be removed), so having Skia use two Wuffs
decoders is unnecessary complexity.
Removing the now-redundant WhichDecoder enum (an enum with only one
possible value), a mechanical change, will be a follow-up commit.
