Emit Event and event.name attribute ambiguity

[pellared]

Another problem, I see in defining Emit an Event method (in scope of this PR) is that there would be an ambiguity what should happen if a user adds an additional event.name attribute. Should the name parameter or event.name attribute have precedence?

PS. The same problem currently exists in https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/logs/event-api.md#emit-event

The Name MUST be used to set the event.name Attribute. If the Attributes provided by the user contain an event.name attribute the value provided in the Name takes precedence.
