Track offsets instead of locations in InterpolationMap (#2674)

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

Add a separate `StylesheetParser.interpolatedStringToken()` method (#2675)

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

Make sure all source spans use interpolation maps (#2673)

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