Add the synchronous gauge to the metric API and SDK (#5304)
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.
