ARROW-8788: [C#] Introduce bit-packed builder for null support in builders This PR improves upon the functionality added in #7032 by replacing nested usage of `BooleanArray.Builder` with a dedicated class `ArrowBuffer.BitPackedBuilder` that works at buffer level. Array builders then use a `ArrowBuffer.BitPackedBuilder` for their validity map, and `BooleanArray.Builder` uses two (one for values, one for validity).
