Description

For scenarios when we need to concate vectors (like the scenario in ARROW-7048, and delta dictionary), we need a way to concat validity bits.

Currently, we have bit level API to read/write individual validity bit. However, it is not efficient , and we need a way to copy more bits at a time.
