[Reg 6.6.2 -> 6.6.3] Qt Quick Controls DLLs are missing from pip packages

Steps to reproduce

1. Create a new .pyproject in Qt Creator ("File" > "New Project..." > "Application (Qt for Python)" > "Qt Quick Application - Empty")
2. Add a single line to the top of main.qml: import QtQuick.Controls.Fusion
3. Run the project

Outcomes
The QML document will fail to load

Analysis

• <VENV_ROOT>/Lib/site-packages/PySide6/qml/QtQuick/Controls/Fusion/qtquickcontrols2fusionstyleplugin.dll depends on Qt6QuickControls2Fusion.dll. This dependency is missing from the PySide6 package.
• The same issue applies to all other Qt Quick Controls styles
• This is a new dependency in Qt 6.6.3 - it did not exist in Qt 6.6.2
