… over-count on batch split When max_export_batch_size splits an export, each split was recording the whole batch's data-point count in the exporter's self-observability metrics (otel.sdk.exporter.metric_data_point.*), over-counting exported/inflight data points. Each split now records its own data-point count.

…ting Use the single _count_data_points helper for both the unsplit request and each split batch, removing the duplicate count loop in export().

Description
Fixes a self-observability bug in the OTLP/HTTP metric exporter: when
max_export_batch_sizesplits an export into multiple requests, each split was recorded with the whole batch's data-point count inotel.sdk.exporter.metric_data_point.{exported,inflight}(opt-in internal metrics), over-counting. Each split now records its own data-point count. This does not affect exported telemetry, only the exporter's own metrics.Type of change
How Has This Been Tested?
max_export_batch_size=1; assert the internalmetric_data_point.exportedcounter totals 3 (previously 9) and 3 requests are sent. Fails on the prior code, passes with the fix.Does This PR Require a Contrib Repo Change?
