### Rationale for this change Closes: #17682 Arrow Boolean arrays store values as individual bits, which is a very compact representation but does not match the layout of many systems with which it interoperates. By adding an 8-bit Boolean extension type, zero-copy compatibility with many systems can be improved at the cost of large physical representation. Go implementation: #43323 C++ / Python implementation: #43488 ### What changes are included in this PR? Proposal and documentation for `Bool8` canonical extension type. ### Are these changes tested? N/A ### Are there any user-facing changes?
