Add support for configuring terms and conditions in device commissioning

This commit introduces a new `enhanced_setup_flow` configuration
property to the test harness backend, allowing device manufacturers to
define the terms and conditions (T&C) that must be acknowledged and set
during device commissioning. These values are critical for supporting
the Terms and Conditions Certification Test Suite.

Key changes include:
- Added the `EnhancedSetupFlowConfig` class to `DutConfig`, which allows
  specifying the T&C version and user response required during
  commissioning.
- Updated `generate_command_arguments` in `utils.py` to append the
  necessary arguments for T&C validation and the device's commissioning
  method.
- Adjusted model validation to ensure the `enhanced_setup_flow` field is
  processed correctly within `DutConfig`.

These changes ensure the test harness can enforce manufacturer-specific
T&C values during the commissioning process, aligning with the broader
requirements of T&C validation.
