Remove dead compile time QML context/scope property and id object code
After enabling lookups in QML files, we can remove all the code that
tries to deal with (type) compile time detection of access to id objects
and properties of the scope/context object. This also allows removing
quite a bit of run-time code paths and even byte code instructions.
Task-number: QTBUG-69898
