GPencil: Refactor Append operators

Now the operators work like other areas of Blender using the list of selected objects.

Also, the name has been changed to:

```Layers:
- Copy Layer to Selected
- Copy All Layers to Selected

Materials:
- Copy Material to Selected
- Copy All Materials to Selected```
