NativeWindow ProxySurface Abstraction and lock/unlock Surface cleanup

- ProxySurface -> abstract javax.media.nativewindow.ProxySurface,
  implemented by
    jogamp.nativewindow.WrappedSurface, just wrapping surface handle
    jogamp.nativewindow.windows.GDISurface, using HWND and get/release HDC on lock/unlock

- Unifying NativeSurface's lockSurface/unlockSurface implementations
    - NEWT's WindowImpl
    - NativeWindow's ProxySurface, WrappedWindow, GDIWindow and JAWTWindow

- wingdi/GDI: Add 'WindowFromDC' and 'GetClientRect' to GDI
