app: add more modifier utility functions to gimpwidgets-utils.[ch]

Browse source 
- gimp_modifiers_to_channel_op() translates a modifier state to REPLACE,
  ADD, SUBTRACT or INTERSECT.

- gimp_replace_virtual_modifiers() uses gdk_keymap_add_virtual_modifiers()
  to replace the physical bits in a modifier state to their virtual
  counterparts (and not just adds the virtual ones like the GDK
  function).
