otlp/translator: Use separate function for metric names with UTF8 characters (#15664)
BuildCompliantName was renamed to BuildCompliantMetricName, and it no longer takes UTF8 support into consideration. It focuses on building a metric name that follows Prometheus conventions. A new function, BuildMetricName, was added to optionally add unit and type suffixes to OTLP metric names without translating any characters to underscores(_).
