Bug 1068, 1096: Unify EGL surface related code in EGLSurface; Add notion of 'Surfaceless Upstream Surface'

Preparation for Bug 1068: GLContext creation and makeCurrent without default framebuffer

- Unify EGL surface related code in EGLSurface
  - EGLWrappedSurface -> EGLSurface,
    which utilizes a more straight forward
    foreign upstream surface (X11, GDI, ..) to EGL mapping.
  This also addresses Bug 1096, i.e. EGL Cleanup.

- Add notion of 'Surfaceless Upstream Surface'
  - Add surfaceless 'fake' upstream surface hooks:
    - EGLUpstreamSurfacelessHook
    - X11UpstreamSurfacelessHook
    Utilizing the ProxySurface option bit 'OPT_UPSTREAM_SURFACELESS'
    signaling usage of 'no surface'.

  - Add GLDrawableFactoryImpl.createSurfacelessImpl(..)
