Migrate the semantic conventions of OpenAI instrumentation to 1.37.0.

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.

Start by reviewing draft PR #14613 and the OpenAI instrumentation changes it proposes, then compare the current implementation with semantic conventions 1.37.0. Done means the instrumentation follows the updated message-event schema, supports the described data-capture configuration options, and includes the additional attributes while addressing the related issues #14783 and #12878.
