Dayue Gao d25f0ba69a Make ColumnReader load lazily (#2026) ...

[Storage][SegmentV2]
Currently `segment_v2::Segment::open` will eagerly initialize all column readers, regardless of whether the column is queried or not. Initializing `segment_v2::ColumnReader` incurs additional I/O cost to read ordinal index and zonemap index and should be delayed to the time it's needed.
