Revert 39530 - GPU plugin forwards repaint events to Pepper plugin.

WM_PAINT results in a call to Pepper repaint callback.
Implemented WM_ERASEBKGND to prevent flickering on repaint.
Implemented PGL_NO_CONTEXT (copied from EGL spec). This is already reviewed by alokp but unfortunately got entangled with this CL.
