[ASTERIXDB-3665]: Compute RangeMap at Compile time
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
- Currently, the RangeMap for range partitioning is computed at runtime
using the full dataset, causing high overhead and complex dynamic
splitting logic.
- This change computes the RangeMap at compile time using sampled data to
simplify splitting and improve performance.
- If no samples are created, parallel sort will not be used.
