Pull Request Overview

This PR removes the redundant tracking of rawInputDataSize and rawInputPositions from the Trino codebase. The key insight is that rawInputDataSize can be calculated as internalNetworkInputDataSize + physicalInputDataSize, and rawInputPositions is redundant with processedInputPositions.

Key changes include:

• Removal of raw input tracking fields from statistics classes
• Update of APIs to use equivalent existing metrics
• Modification of tests to reflect the new data structure
