Added Prehook option to prepare method (#41863)
Summary:
Added a logic so that if a prehook is passed into the prepare method during quantization, then the hook will be added as a prehook to all leaf nodes (and modules specified in the non_leaf_module_list).
Pull Request resolved: https://github.com/pytorch/pytorch/pull/41863
Test Plan:
Small demo, made simple module then called prepare with prehook parameter set to the numeric suite logger, printed the results to verify its what we wanted
