Invoke TensorExpr fuser pass from a graph executor. (#35913)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/35913
The pass itself is still disabled by default, but with this change we
don't need to register it as a custom pass anymore. It allows us to
control its behavior with env variables more easily.
