Make callback in BrowserGpuClientDelegate non-member function

BrowserGpuClientDelegate might have been destroyed when
OnEstablishGpuChannel callback is run. Although this callback does not
use |this| and just runs the other callback passed to it, it is
technically an undefined behavior. Making it a non-member function,
helps us avoid this undefined behavior.
