wxDisplay cleanup/rewrite:

- wxDisplay is now a concrete class and uses a pImpl-based design
- got rid of four duplicate but subtly different versions of trivial
  single display-only wxDisplay implementation (but 2 versions of Mac
  Classic and Mac CoreGraphics implementations each still remain...)
- assorted code simplifications and memory leaks fixes
