More validation tests

[mkorman90]

• Add validation tests for all plugins with tests
• Support custom tests

  # Optionally Implement a custom test for your plugin, which will be called during the validation step
  # This test can replace the validation of entries, but not the count.
  # The test must return True, or raise an AssertionError
  custom_test: Optional[Callable] = None

• There are currently 7 plugins without a validation case:

[!] 7/39 plugins have no validation case!	plugin_name	plugin_class_name	test_case_name	success
routes	RoutesPlugin		False
timezone_data	TimezoneDataPlugin		False
image_file_execution_options	ImageFileExecutionOptions		False
active_control_set	ActiveControlSetPlugin		False
safeboot_configuration	SafeBootConfigurationPlugin		False
installed_programs_ntuser	InstalledProgramsNTUserPlugin		False
terminal_services_history	TSClientPlugin		False

• Prepared the framework for enforcing validation in the future, all is left is flipping a switch in regipy_tests/validation/plugin_validation.py:

  ENFORCE_VALIDATION = True

  which will currently cause the validation step (and thus the build) to fail:

  
  ...
