[QGIS-Developer] Creating & loading Qt6 resource files for python plugins

[Benjamin Jakimow]

Dear Experts,

for our QGIS Python plugins we load icons into the Qt Resource system, 
so that they can be accessed as in QIcon(r':/myplugin/myicon.svg').

In PyQt5 / QGIS3 we do this by:
1. compiling myresource.qrc files into a myresource_rc.py file, either 
using pyrcc5 (on CLI) or qgis.PyQt.pyrcc_main (in Python).
2. loading these icons on plugin start-up, like in:

   import myresource_rc
   myresource_rc.qInitResources()

It seems that in QGIS4 / Qt6 neither pyrcc5 nor qgis.PyQt.pyrcc_main is 
available (tested in OSGeo4W qgis-qt6 environment).

It's possible to create *_rc.py files using pyside6-rcc, but they use
from PySide6 import QtCore
which is not available (e.g. in the current OSGeo4W qgis-qt6 environment).

Does anyone have an idea how we can create Qt6-style *._rc.py files 
instead?

Greetings, Benjamin
