[core][DV] Support obtain row position when reading orc and parquet

[Zouxxyy]

Purpose

This is the first step of #2898, in this PR:

• add new config deletion-vectors.enabled which default is false and should only be used with PK table and orc/parquet format currently
• add system col _ROW_POSITION
• add rowPosition in KeyValue and set it when deletion-vectors.enabled is true
• support obtain rowPosition when reading orc and parquet

Tests

API and Format

In my opinion, having an additional field for KeyValue may have a significant impact, for example, after Merging, this field will be meaningless.

A less invasive approach could be to introduce a new RecordReader.RecordIterator, for example, adding the RecordWithPositionIterator class:

public interface RecordWithPositionIterator<T> extends RecordIterator<T> {
    long currentPosition();
}
