Subject: Reimplement Qt5 OpacityMask using Qt6 MultiEffect

https://darapsa.org/qessenger.git/commit/?id=5f777bca13beadd0a56d2264225b0c09e49541a2
The mask Rectangle needs to be put outside of the MultiEffect,
and referred to by the Rectangle's ID.
It wouldn't work if it's put directly on MultiEffect's maskSource.

https://forum.qt.io/topic/145956/rounded-image-in-qt6
Enabling layer and invisibility on the mask rectangle are a must.
Take notice on what Jacoco wrote about jagged edges at the end of the
thread. Will test that later.
