Subject: [PATCH 111/153] Fix qml cache invalidation when changing dependent
C++ registered QML singletons
When a qml file uses a qml singleton, we need to reliably detect when
the singleton changes and re-generate the cache of the qml file using
it. This is a scenario covered and fixed by commit
5b94de09cc738837d1539e28b3c0dccd17c18d29, with the exception that
currently QML singletons registered via qmlRegisterSingleton were not
added to the list of dependent singletons for a qml file. We can fix
this by extending findCompositeSingletons() to also cover the singletons
that do not originate from a qmldir file.
[ChangeLog][Qt][Qml] Fixed bug where sometimes changes to a qml
singleton would not propagate to the users or cause crashes.
Task-number: QTBUG-62243
