Problem Statement

Currently, there is no way to define instrumentation scope attributes when creating a tracer/meter as specified in https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/api.md#get-a-meter

Proposed Solution

Add back instrumentation scope attributes.

Prior Art

This was already implemented by #3132 but it was reverted because specs was not ready yet (#3154).
