/**
* Returns monotonically increasing 64-bit integers.
*
* The generated ID is guaranteed to be monotonically increasing and unique, but not consecutive.
* The current implementation puts the partition ID in the upper 31 bits, and the lower 33 bits
* represent the record number within each partition. The assumption is that the data frame has
* less than 1 billion partitions, and each partition has less than 8 billion records.
*
* Since this expression is stateful, it cannot be a case object.

Idea: Maintain partition_id in the query context of CH and develop built-in functions in gluten cpp
