Tyler Yahn 88d3fedf1a Optimize the return type of ExportSpans (#7405 )

Do not allocate a return function from `ExportSpans` to the heap. Use
the added `ExportOp` type instead.

OpenTelemetry Exporters

Once the OpenTelemetry SDK has created and processed telemetry, it needs to be exported. This package contains exporters for this purpose.

Exporter Packages

The following exporter packages are provided with the following OpenTelemetry signal support.
