Move dag_processing.last_run.seconds_ago.{dag_file} to a tagged metric
dag_processing.last_run.seconds_ago with file_path, bundle_name and
file_name tags. file_path and bundle_name together uniquely identify a
DAG file (the same file name can exist in different folders or bundles),
and file_name is kept as a tag to ease migration from the legacy metric.
The legacy interpolated name is registered as the metric's legacy_name,
so it is still emitted by default (controlled by [metrics] legacy_names_on),
preserving backward compatibility.
