Breaking changes to component.InstanceID

[mwear]

There is an in-progress PR to make component.InstanceID immutable in collector core. It is currently a struct with all fields exported. The fields will only be accessible by getter methods going forward. Here are the occurrences of component.InstanceID in this repo: https://github.com/search?q=repo%3Agrafana%2Fagent%20component.InstanceID&type=code.

I believe the only thing that will have to change is:https://github.com/grafana/agent/blob/3eb7f7e314bbd3084770e8ed214ddedf3062bf66/internal/converter/internal/otelcolconvert/utils.go#L14-L16

The change that will need to be made is below:

func StringifyInstanceID(id component.InstanceID) string {
	return fmt.Sprintf("%s/%s", StringifyKind(id.Kind()), id.ComponentID())
}

Hi, @mwear! Thank you for the heads up! 😊 Please feel free to merge the OTel PR when it is ready, and we will update Agent and Alloy accordingly during the next time we upgrade the OTel dependencies. I think it shouldn't be a problem.
