Migrate the semantic conventions of OpenAI instrumentation to 1.37.0.

[Cirilla-zmh]

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

The implementation of the OpenAI instrumentation is based on semconv version 1.36.0, which includes significant updates in version 1.37.0, such as redefining the schema of message events, introducing configuration options to control data-capturing behaviors, and adding more important attributes.

Describe the solution you'd like

I believe we need to refactor the OpenAI instrumentation to align with the latest semantic conventions for capturing chat messages. I have previously submitted a draft PR for this. If possible, I hope to resolve this issue, as it will also benefit the development of #14783 and #12878.

Thanks @Cirilla-zmh - AFAIK this should still be alpha and we can change it any way. I'd recommend refactoring to the latest conventions without too much consideration following the general version policy. Let me know if I can help with it.
