MLIA-688 Fix --supported-ops-report flag

* Add `api.generate_supported_operators_report` that calls
  a report generator based on given target profile.
* Update `--supported-ops-report` cli flag help section and README.md
  info by specifying that it is currently only supported for Ethos-U.
* Add tests for `generate_supported_operators_report` method.
* Add stub methods `report` for Cortex-A
  and Tosa operators.py module that throw a "Not supported" exception.
