[exporter/elasticsearch] Use a single instance of esExporter for all event types

Describe the issue you're reporting

With #33318 both logs and traces exporter will be unified to use the newly introduced esExporter, however, it will still create a new instance of the esExporter for each event type. This leads to additional overhead to maintain more bulk indexers. Refactor the code using SharedComponent or a similar method to create a single instance of the esExporter for all event types.
