All attributes should be passed from span to operation listerners

Describe the bug

Currently we are passing only the span attributes which are extracted from AttributeExtractor to the operational listeners while we leave the attributes which are let us say added by the users additionally for their own tracking purposes.

Now since we have recently integrated the advice API, this allows views to override advice but then views api with the above issue can only be used to filter out existing attributes or only add attributes which are part of the attribute extractor but not the ones which are added by the user.

https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/23a6a3e2c017d531623ee22dbbe426e8bf160dd9/instrumentation-api/src/main/java/io/opentelemetry/instrumentation/api/instrumenter/Instrumenter.java#L224C22-L237

We can check this part of the code which higlights the issue, because of this while a tracing signal has all the attributes but the metric signal is missing the reamining attributes and hence a user face limitations.

Steps to reproduce

We can add a custom attribute to a span and create a view which expose it, we will not get this attribute.

Expected behavior

We should pass all the span attributes to operation listeners

Actual behavior

We are only passing the attributes extracted by AttributesExtractor

Additional context

No response

Start in instrumentation-api/src/main/java/io/opentelemetry/instrumentation/api/instrumenter/Instrumenter.java at the linked lines and review how span attributes reach operation listeners. Reproduce the case with a custom span attribute and a view that exposes it. Done means operation listeners receive all span attributes, including user-added ones, rather than only extracted attributes.
