Re-factoring of rewrite management & added metrics

- List available rewrites
  - Refactor/rename 'Rewrite' class to 'RewritingOptimizer'
  - Introduce a registry for rewrite functions
  - Refactor 'Rewriter' to use the registry to look up rewrite functions
  - Remove mentions of hardcoded "fully_connected" from CLI help and
    error messages, using the registry instead
  - Add unit tests
- Enable rewrites for all targets:
  Extract optimization (including rewrite specific code) from the
  Ethos-U-specific data collector into OptimizingDataCollector.
  This is reused in other targets' collectors, such as TOSA
  and Cortex-A.
- Add more logging for rewrite
  - add display of MAE and NRMSE values for the trained result
  - add total model MAE and NRMSE metric

Resolves: MLIA-891, MLIA-899, MLIA-906
