[QGIS-Developer] Apply style to all selected layers and groups

[C Hamilton]

The other aspect of this that I didn't mention is that my users create
their own styles which they save ("Save Symbol") under their own tags. This
is all available under the "Layer Styling" panel. When they click on one of
their styles they would like it applied to all selected layers, but because
this is under "Layer Styling" it is only applied to one layer.
