Introduce QQmlApplicationEngine::loadFromModule

This allow instantiating QML types via their module and typename. It
simply exposes the underlying functionality of
QQmlComponent::loadFromModule.
Also add the corresponding convenience constructor.

This commit also does some minor refactoring so that functionality can
be shared between load and loadFromModule.

[ChangeLog][QtQml][QQmlApplicationEngine] It is now possible to load QML
types via their module and type name.

Fixes: QTBUG-97156
