TextEditors: Separate away methods that actually work on a document

Introduces ITextEditorDocument. This is part of a more general "use
documents instead of editors whereever possible". It will allow to move
to e.g. ITextEditor::openedTextDocumentContents() instead of
ITextEditor::openedTextEditorsContents().
