Event identifier of an integer type

[pellared]

What are you trying to achieve?

It may be good to allow having EventId of an integer type (instead of EventName which is always as string) for performance reasons.

Additional context.

In .NET the EventId is a integer with optional name.

I created this issue as I think it was brought up a few times.

My personal opinion, is that for sake of simplicity we should only have Event Name as string for the identifier. The reason is that it is the model of OpenTelemetry Events and not any possible event system/library/software. The OTel Semantic Conventions are using names.
