Fix connecting to signals with QFlags<>

Additionally register the shiboken converter under the type alias
name ("Qt::Alignment"), which appears in the meta method signature
besides the full name ("QFlags<Qt::AlignmentFlag>").

Manifests as signal:
QBluetoothDeviceDiscoveryAgent::deviceUpdated(QBluetoothDeviceInfo, QBluetoothDeviceInfo::Fields)

Pick-to: 6.6
Fixes: PYSIDE-2613
