[ao] Added ModelReport class outline for Fx Graph Modules
Summary: The ModelReport class in model_report.py combines the
functionality of the detectors and the ModelReportObserver. It creates
an end-to-end system where a user can pass in a prepared Graph Model to
insert the ModelReportObservers, then after the user callibrates their
model, the callibrated model can then be used by the ModelReport class
to generate reports based on what the user wished to gather information
on.
This contains the init method and the signatures and docs for each
of the proposed helper functions.
This also address and fixes a revert issue.
Test Plan: python test/test_quantization.py TestFxModelReportClass
