Hui Xiao 629605d645 Move prefetching responsibility to page cache for compaction read under non directIO usecase (#11631) 
Summary:
**Context/Summary**
As titled. The benefit of doing so is to explicitly call readahead() instead of relying page cache behavior for compaction read when we know that we most likely need readahead as compaction read is sequential read .

**Test**
Extended the existing UT to cover compaction read case
