Add ability to retrieve and use the QmlContext from our generated code

Our generated code (JIT and interpreter) should operate on the
QML context to retrieve QML related things. That's better than
operating on 4 different temps.

So this commit introduces the QML context as a temp in the
code we generate for QML. The next commits will move things over
to use that context with specialized runtime methods instead of
using generic subscript/get calls on the different subobjects.
