incubating OTel APIs can't be used it the agent

Is your feature request related to a problem? Please describe.

ApplicationTracer doesn't implement ExtendedTracer - similar for other APIs

https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/instrumentation/opentelemetry-api/opentelemetry-api-1.0/javaagent/src/main/java/io/opentelemetry/javaagent/instrumentation/opentelemetryapi/trace/ApplicationTracer.java

In the SDK, there's a similarly surprising problem: open-telemetry/opentelemetry-java#6617

A first part (for metrics) was already implemented in the agent: #11934
The second part (that also covers noop) can be implemented once the SDK issue has been fixed.

Why the dependency?
The agent uses noop if there are no readers registered: https://github.com/open-telemetry/opentelemetry-java/blob/c33febbea6250d771d2081637764c25ddd071875/sdk/metrics/src/main/java/io/opentelemetry/sdk/metrics/SdkMeterProvider.java#L111

Describe the solution you'd like

User should be able to just use incubating API if they add the dependency
