Context missing from http server / client content length metrics

[anuragagarwal561994]

Describe the bug
Context is not passed while recording metrics for content length metrics for http server and client.

Because of this if a baggage view is applied to the meter, it is not available to the attribute processor which is trying to read from the context as the context might have been changed (in async cases especially) because by default we are using Context.current().

What did you expect to see?
Context should be passed to the context length metrics to be able to fetch the data from baggage api that is present in the current context.

What version are you using?
1.19.0
