Big wxGL classes refactoring/cleanup:

1. Provide the same API, especially, but not limited to, wxGLCanvas and
   wxCLContext ctors (which were completely different in all ports)
2. Extracted common parts into wxGLCanvas/ContextBase classes
3. Deprecate the old API using implicitly created wxGLContext
