[CI] Implement CI check to ensure the data model build files match the ones in the dir

[cecille]

Reproduction steps / Feature

The files listed in https://github.com/project-chip/connectedhomeip/blob/master/src/python_testing/matter_testing_infrastructure/data_model_xmls.gni should match the file set in https://github.com/project-chip/connectedhomeip/tree/master/data_model and the CI should enforce that.

Can add to the data model checker in https://github.com/project-chip/connectedhomeip/blob/master/scripts/dm_xml_ci_change_enforcement.py as this already runs in the CI.
