🔨 v2 - Refactor: Add missing auxiliary attributes to AnomalibModule

[samet-akcay]

📝 Description

This pull request introduces enhancements to the AnomalibModule and Engine classes within the Anomalib library. The changes standardize the component configuration pattern across pre-processors, post-processors, evaluators, and visualizers, with a particular focus on refactoring the post-processor implementation.

✨ Changes

1. Post-Processor Refactoring:

   • Added _resolve_post_processor method to standardize post-processor configuration
   • Introduced configure_post_processor classmethod to provide default post-processor setup
   • Implemented learning-type-based post-processor configuration (e.g., OneClassPostProcessor for one-class learning)
   • Added type validation and error handling for post-processor configuration

2. Component Configuration Pattern:

   • Standardized the configuration pattern across all components using resolve/configure methods:

     _resolve_<component>: Handles type validation and resolution
     configure_<component>: Provides default configuration

   • Updated configure_callbacks to handle all components uniformly
   • Components now support three configuration modes:
     • True: Use default configuration
     • False: Disable the component
     • Component instance: Use provided configuration

3. Documentation and Type Hints:

   • Added comprehensive docstrings with usage examples
