Rewrites tessellation atlases as normal render tasks instead of
"onFlush" tasks. These tasks get inserted into the DAG upfront, lay
out their atlases as dependent tasks get built and reference them, and
finally add their ops to render themselves during onMakeClosed. Doing it
this way allows us to pause the flush and re-render the atlas whenever
it runs out of room.

inversion logic.
Support for 2x2 and 3x3 matrix inversion was also added to
SkMatrixInvert, but is not currently used anywhere in Skia besides
optimize_intrinsic_call. (The perspective case of SkMatrix::ComputeInv
could probably be adapted to use the shared 3x3 code.)

Awkwardly, there is still two copies of (some of) this SkSL. We have
helper functions in SkRuntimeEffectPriv.h that implement these
transformations, and those are used by the high contrast color filter.
However: The RGB to HSL code is fairly different, and produces results
that are visibly different. For this CL, I didn't want to impact either
use case, so this is just a migration of the existing .fp code (only
used by HSLA color matrices). We can/should look at merging the
implementation in the future.

Like SkColorFilter, SkShader, etc., this has a public-facing component
(SkBlender) and a private subclass (SkBlenderBase) which can be
obtained via a helper function (as_BB). At present there are no public-
facing methods, but the type needs to be exposed to be usable by the
outside world.
These classes exist for SkRuntimeEffect to subclass. The blender base
provides a `program` method with the parameters that blending will use.

Previously, when converting a program, the pipeline stage could assume
that an input to main() of type half4/float4 was always the input color.
This was a good assumption since the only possible inputs were
coordinates, or the input color.
This CL now recognizes that when a second float4 is passed to the main()
function, it should be a SK_DEST_COLOR_BUILTIN. This will let blend
functions pass in two colors.
ProgramToSkVM now takes a dest-color argument as well, but existing call
sites won't reference it (since they aren't for blend functions). I've
just passed the input-color a second time, since the value will never
actually be accessed.
