Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Just as what we have done in the PrimitiveBuilder: https://github.com/apache/arrow-rs/blob/master/arrow/src/array/builder/primitive_builder.rs#L33-L35
We could put this optimization in the BooleanBuilder

Describe the solution you'd like
A clear and concise description of what you want to happen.

Describe alternatives you've considered
I don't know why we only do this optimization for primitive builder. If there are some context or reasons, we could not do this.
