Allow TimedAspect/CountedAspect to create tags based on method result

[kevinkraus]

Please describe the feature request.
Update TimedAspect to allow injecting a Function to create tags based on method result, similar to the Function injected to create tags based on ProceedingJoinPoint.

Rationale
I am using the Timed annotation and would like to include information from the Object returned by the target method in the tags.

Additional context
I'm willing to submit a PR for this enhancement.

Hi, any news on this? I think that would be really interesting, not just for TimedAspect but for CountedAspect as well. I'm also willing to participate in the implementation.

We already have it since 1.7.0? https://github.com/micrometer-metrics/micrometer/blob/v1.12.1/micrometer-core/src/main/java/io/micrometer/core/aop/TimedAspect.java#L156 Or am I missing sth?

This seems to suggest adding a function that provides tags from the return value of ProceedingJoinPoint.proceed() while Micrometer currently supports a function that provides tags from ProceedingJoinPoint.
