Mark correct tree-scope dirty removing link in shadow.

Mark correct tree-scope dirty removing link in shadow.

Noticed while working on 567021, StyleElement found the correct
tree-scope in from of a shadow root when applicable while
HTMLLinkElement would just use the document. This is what kept us from
being able to use AnalyzedStyleUpdate for removedFrom() for link
elements.
