With the intent of using it in UI tests (#67122).
The option is boolean (
-Z deduplicate-diagnostics=yes/no) and can be specified multiple times with later values overriding earlier values (-Z deduplicate-diagnostics=no -Z deduplicate-diagnostics=yes==-Z deduplicate-diagnostics=yes), so it can be set in a hierarchical way, e.g. UI testing infra may disable the deduplication by default with specific tests being able to enable it back.
