 #!CommitTicketReference repository="" revision="50641"
 Docs: Clarify return results for a non-existing ID in metadata functions.

 [48658] documented that various metadata functions return false for an
 invalid ID. However, that does not clarify what an invalid ID is: a non-
 numeric, zero, or negative value. This change adds the clarification in
 all relevant metadata function docblocks.

 Props icopydoc, SergeyBiryukov, davidkryzaniak, audrasjb.
 Fixes #51797.
