Reduce string allocation in DiagnosticCounter.GetMetadataString (#25219)

When the _metadata dictionary contains a single key/value pair, the method ends up allocating an unnecessary StringBuilder, char[] beneath it, and input string.

When the _metadata dictionary contains more key/value pairs, the method ends up allocating an unnecessary string per key/value pair.
