There was some idea that we'd substitute the paint color for the missing
input shader. However, the implementation (CPU) would also apply
the paint's alpha after the blend shader, meaning the alpha was used
twice.
If a caller wants to blend a shader against a constant color there are
already at least two ways:
1) SkColorFilters::Blend()
2) SkShaders::Blend() where one input is SkShaders::Color().
Rather than come up with a more rational implementation for CPU and
make GPU follow suit, just make this invalid input and return nullptr.

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.

We still need *a* copy, to satisfy SkSL that mutates the input color
parameter, but it almost never needs to be global, unless there are
calls to sample() from a function other than main.
With that tweak, we generate much better SkSL/GLSL code from every one
of our effects, avoiding the proliferation of global variables.

Tessellation uses infinity to flag conics, and also as a conic weight
that converts them into triangles. The es2 shading language doesn't
support infinity. This CL adds a "portable infinity" mode, where we
pretend inputs >= 2^126 are infinity. The rationale for doing this is
that those numbers are so large, they will overflow if we try to do any
bezier math with then anyway.

The SkTypeface_FreeType::FaceRec destructor should always have asserted
that the f_t_mutex was held (like all other methods of FaceRec) instead
of attempting to take the mutex on behalf of the user of the FaceRec. As
a result of attempting to take the mutex it was an error to ever delete
a FaceRec when holding the mutex (like in FaceRec::Make).
Move the taking of the mutex to SkTypeface_FreeType, which is the owner
and user of the FaceRec.
