[CSS Shape function] Support interpolation between path() and shape()
https://bugs.webkit.org/show_bug.cgi?id=277709
rdar://133325334
Reviewed by Antti Koivisto.
Support interpolation between `path()` and `shape()` functions as described in
[1], where the output is
a `shape()`.
Have `BasicShapePath::canBlend()` and `BasicShapeShape::canBlend()` check to
see if the other object
is something that can be blended with, then call into `canBlendWithPath()`.
This creates a temporary
BasicShapeShape object to answer the question.
Implement `BasicShapeShape::createFromPath()` to create a BasicShapeShape from
a BasicShapePath, using a
`SVGPathParser` with a custom `SVGPathConsumer`. Note an ambiguity in the spec
[2] around initial Move
commands vs the "from" in `shape()`.
