Resolve an issue in where metric names were lost when splitting objects. Updated logic now ensures all metric fields, including names, are retained across splitting operations. Added relevant tests to validate the fix.

Ensure metric metadata is copied when splitting data points by adding a `CopyTo` call. Added comprehensive test coverage to verify correct behavior for various metric types and scenarios.
Previously, RequestSizerTypeBytes was calculating datapoint size incorrectly due to the omission of 'name', 'description', and 'unit' fields. This commit rectifies the calculation by including these fields.

This update ensures that metadata is copied from source to destination metrics during transformation. Tests have been updated to validate metadata handling, including verifying key-value pairs in the metadata.

Description
This PR fixes an issue in exporter/exporterhelper's sending_queue where metric names were lost during metricRequest splitting. Previously, when large batches of metrics were processed, the splitting logic in metric_batch.go could cause the name field of some metrics to disappear. This fix ensures that all metric fields are properly preserved when metricRequest objects are split.
