ian f556bd3211 prometheus: use a sync.Pool instead of allocating metricdata.ResourceMetrics in Collect (#6472 )

Fix #3047 

Use a `sync.Pool` instead of allocating `metricdata.ResourceMetrics` in
`go.opentelemetry.io/otel/exporters/prometheus`

```shell
goos: darwin
goarch: arm64
pkg: go.opentelemetry.io/otel/exporters/prometheus
