Description

Steps to reproduce

$ ../installed/bin/qt-cmake ~/dev/qtdeclarative/examples/quickcontrols2/gallery/
$ ninja
$ ./gallery_controls2.app/Contents/MacOS/gallery_controls2 -> runs fine
$ ../installed/bin/macdeployqt ./gallery_controls2.app -qmldir=~/dev/qtdeclarative/examples/quickcontrols2/gallery/
$ ./gallery_controls2.app/Contents/MacOS/gallery_controls2 -> fails

Fails with

./gallery_controls2.app/Contents/MacOS/gallery_controls2
QQmlApplicationEngine failed to load component
qrc:/gallery.qml:58:1: Type ApplicationWindow unavailable
qrc:/qt-project.org/imports/QtQuick/Controls/Fusion/ApplicationWindow.qml:41:1: module "QtQuick.Controls.Fusion.impl" plugin "implplugin" not found

When running macdeloyqt the following warnings are shown.

macdeployqt skips similarly named plugin libraries despite them being associated with a different qml module

I guess it does that because it's flattening / copying each .dylib into Contents/PlugIns/quick/
but then creates a symlink under the Resources folders to recreate the qml import path.

I guess we need to specify unique file names for each of those impl plugins.
