a8ac441411 Move Mode() factory into SkBlender
This frees the SkBlenders names for optional effects, and better
reflects the fact that the "core" relies on this Mode() factory.

... and makes this clearer:
https://skia-review.googlesource.com/c/skia/+/424417

Maybe this isn't important. I see SkShaders is in core header, but
SkImageFilters is in effects, so I guess we don't have a consistent
notion for this naming yet. What I do think is semi-important is
that core headers include effects that core uses, so in this case
a Mode() factory does make sense to be in a core header, just have to
decide/bikeshed how to scope it.

2d8b835cad Add SkBlender class; thread into SkVMBlitter.
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.
