use `check_region_obligations_and_report_errors` to avoid ICEs

If we don't call `process_registered_region_obligations` before `resolve_regions_and_report_errors` then we'll ICE if we have any region obligations, and `check_region_obligations_and_report_errors` just does both of these for us in a nice convenient function.

Fixes #53475
