Refactoring: Generalize CachedSVGDocument for non-SVG use.

Refactoring: Generalize CachedSVGDocument for non-SVG use.

This change generalizes CachedSVGDocument to CachedDocument,
which manages Document instead of Document.
Currently, CachedDocument implementation accepts only SVG.
Further changes will follow.

This is a preparation for HTML Imports implementation.

Dimitri, Adam, could you take a look?
This change doesn't change behaviour.
It's another preparation for HTML Imports.
