Refine some metrics in parquet reader profile.
1. Rename some `Statistics` class name to make it readable. (There are
too many `Statistics` struct with same name)
2. Add `read page header timer` in parquet reader profile
3. fix issue of invalid check logic for `MergeRangeFileReader` when
setting prefetch buffer size
4. fix issue that data cache profile is incorrect for external table
