`Scanner.spanFrom` doesn't respect Sass's `InterpolationMap`, so this
changes all span accesses to go through `Parser.spanFrom` and
`Parser.spanFromPosition`.

…2675)

Unlike `StringExpression.asInterpolation()`, this ensures that the
text between interpolated expressions exactly matches the text in the
original document.

This is semantically identical, but a little more efficient and easier
to construct in situations without actual `SourceLocation`s.

See #2197

This adds a separate "interpolated selector" AST that parallels the
existing selector AST, but includes the interpolation that's present
in the source files. This AST isn't used by the Sass implementation
itself; it's just made available so that tools can gracefully interact
with selectors as an AST in unevaluated Sass files.
