Subject: Make Behaviors work correctly with value types.

When a value type is referenced by sub-component a grouped
property is built. This code path did not handle behaviors being
declared on the entire value type. Add support for value interceptors
in this code path. Also issue an additional write to the value
type property before calling the interceptor on components
that are not being intercepted, so that the other
sub-components don't get stale values during write back.

Task-number: QTBUG-22625
Change-Id: I3365f422dfa1ab2e536e19575efcceceffb85e10
