Diagnostic metadata for the failed token-acquisition attempt — the total duration and, when the
relevant stage ran, HTTP/cache durations, token endpoint, and region used. This is
null when the exception was thrown before the request pipeline started collecting
metadata (for example, parameter or builder validation). When it is non-null — the typical
in-request failure — DurationTotalInMs is always
populated (useful for latency measurement), while the other fields may be 0/null when the
corresponding stage did not run. On a failure
TokenSource has no meaningful value and should not be
relied on. Reuses the type returned by AuthenticationResultMetadata
on the success path.

Remarks
Populated in-process after the request completes; it is intentionally not part of the exception's JSON serialization, so it is not preserved if the exception is marshaled across a process boundary.
