enhance: Add MAP_POPULATE flag for mmap to reduce page faults (#46761) ...

Add configurable MAP_POPULATE flag support for mmap operations to reduce
page faults and improve first read performance.

Key changes:
- Add `queryNode.mmap.populate` config (default: true) to control
MAP_POPULATE flag usage
- Add `mmap_populate` parameter to MmapChunkTarget, ChunkTranslator,
GroupChunkTranslator, and ManifestGroupTranslator
- Apply MAP_POPULATE to both MmapChunkTarget and MemChunkTarget
- Propagate mmap_populate setting through chunk creation pipeline

When enabled, MAP_POPULATE pre-faults the mapped pages into memory,
eliminating page faults during subsequent access and improving query
performance for the first read operations.

issue: #46760
