  [WebGPU] Crash PresentationContextIOSurface::getCurrentTexture if context is not configured

Reviewed by Dan Glastonbury.

An IPC call made directly to getCurrentTexture may result in a scenario where
the IOSurfaces have not yet been created. In this case, we want to return nullptr
to the caller.
