pkg/exporterhelper: Add the pkg.exporterhelper.queueBatchEnabled feature gate (#14038, #13582, #12022)
When enabled, the batch settings returned by NewDefaultQueueConfig() have
batch::enabled true. See migration RFC.

pkg/exporterhelper: Record otelcol_exporter_queue_batch_send_size and otelcol_exporter_queue_batch_send_size_bytes after batching, and add otelcol_exporter_enqueue_size and otelcol_exporter_enqueue_size_bytes for enqueue-time sizes. (#14674)
Previously the batch send size histograms were recorded at enqueue time (Offer), so they
measured incoming request sizes rather than the post-batching request handed to the
downstream sender. Those histograms are now recorded in the obs report sender.
The previous enqueue-time measurements are preserved under the new
otelcol_exporter_enqueue_size and otelcol_exporter_enqueue_size_bytes metrics for
queue sizing. Users with the exporter batcher enabled will observe different values for
otelcol_exporter_queue_batch_send_size*.
otelcol_exporter_queue_batch_send_size and otelcol_exporter_queue_batch_send_size_bytes
are now only recorded when sending_queue::batch is configured; they will not appear at all
for exporters that do not enable batching.
pkg/scraperhelper: Use {record} instead of {datapoint} as the unit of the log record and profile record scraper metrics (#15730)
Affects otelcol_scraper_scraped_log_records, otelcol_scraper_errored_log_records,
otelcol_scraper_scraped_profile_records and otelcol_scraper_errored_profile_records.
