Resolve #5225 The specification has [added a synchronous gauge instrument](https://github.com/open-telemetry/opentelemetry-specification/pull/3540). That instrument has now been [stabilized](https://github.com/open-telemetry/opentelemetry-specification/pull/4019), and that stabilization is included in the [next release](https://github.com/open-telemetry/opentelemetry-specification/pull/4034). This adds the new synchronous gauge instrument to the metric API and all implementation we publish. This change will be a breaking change for any SDK developer. The `embedded` package is updated to ensure our compatibility guarantees are meet. --------- Co-authored-by: David Ashpole <dashpole@google.com>
