qmllint: Check for existence of property types

For each binding there should be a property and that property should
have a type we recognize.

Enums can be property types in C++. We support this by adding child
scopes for such enums. The child scopes are then referenced by the
QQmlJSMetaEnums and derive from int.

The test then reveals that we were missing a few properties in
QtQuick.tooling. Add those.
