Initialize the extension bindings in g_driver_egl

This step is done in GLSurfaceEGL but missing in GLSurfaceEGLQt.
The extension bindings in g_driver_egl are checked, among other things,
when initializing DXVAVideoDecodeAccelerator, so we need them to enable
hardware-accelerated video decoding on Windows with ANGLE.
