Refactor(pyavd): Refactor backend ANTA code of PyAVD

[carl-baillargeon]

Change Summary

Refactor and reorganize backend ANTA code of PyAVD.

Component(s) name

PyAVD

Proposed changes

1- Converted Pydantic models to dataclasses and updated class names to follow our codebase
2- Removed the conditional_keys field from AvdTestSpec to use the new skip_if_missing_config decorator instead
3- Also added the relevant input factories that use the new decorator
4- Removed ignore_is_deployed knob from AvdCatalogGenerationSettings - users can simply look for the is_deployed key prior to calling get_device_test_catalog
5- Moved the filtering logic of AvdTestSpec to a function in utils to simplify get_device_test_catalog
6- Moved the creation of InputFactoryDataSource (previously DeviceTestContext) to get_device_test_catalog
7- Removed perf_counter leftover logs from a previous PR

How to test

anta_runner molecule.
