Fix #10648 (add layer to the selected group)
Hopefully fix #10599 (blank composer map when rendering rasters)

When printing on Windows, the printing does not seem to work
well in the worker thread as QImages get converted to QPixmaps.
Therefore we force the map rendering into main thread to avoid the issues.

I do not have a printer, so I can't confirm the fix really helps

Editor widgets: Change default "enable sync" behavior

More generic implementation of 024cd0b

EditorWidgetWrappers (which are connected to fields) are synced with
the layer edit mode state.
WidgetWrappers (which are not strictly related to fields being editable)
don't sync their edit state to the layer edit mode state.
