Add qml6-module-org-kde-breeze in mobian-phosh-extras and mobian-plasma-mobile-base

Marco Mattiolo requested to merge tiol/meta-mobian:wip/tiol/qml6breeze into mobian

There is a IMO-recurrent complaint in the Mobian room about Qt-based apps failing to start on Mobian systems due to missing org.kde.breeze style. It started with nheko, because the Qt6-based version was uploaded in Debian way before the Qt6 version of breeze. Needed package is qml6-module-org-kde-breeze.

I've been wondering whether we should rather drop QT_QUICK_CONTROLS_STYLE=org.kde.breeze from common/profile.d/mobile-tweaks.sh or mandate qml6-module-org-kde-breeze to be installed.

AFAICT installing qml6-module-org-kde-breeze would require additional 67MB space in Mobian systems

mobian@mobian:~$ sudo apt install qml6-module-org-kde-breeze

On the other hand, I've tested qmlkonsole in a Phosh environment and it seems to need qml6-module-org-kde-breeze regardless of the QT_QUICK_CONTROLS_STYLE variable

I'm going to check the qmlkonsole issue with Qt/KDE folks, but to stay on the safe side, I'd require qml6-module-org-kde-breeze on every system...
