qmlls: enabled/disable embedded codemodel

Make the (de)activateDocument() method in Client virtual, and override
it in QmllsClient to actually be able to enable or disable the embedded
codemodel.

Also add a setSourcesWithCapabilities method to QmlJSEditorDocument that
calls the same-named method in QmlJSEditorDocumentPrivate.
