Subject: Speed up V4 QML context creation

After commit cae7975a036352ca4bbcf1381a445362f8e01367 the vtable became
part of the internal class, which meant that for allocating the
V4::QmlContext and the QV4::QmlContextWrapper we had one additional IC
transition upon allocation. We can avoid that by providing a default IC
for both types.

Task-number: QTBUG-65708
