GH-34094: [C++] Increase Boost minimum version for clang >= 16 (#34100)
### Rationale for this change
Build fails with older Boost on Clang >= 16
### Are there any user-facing changes?
No our dependency management will download the required Boost version if it is not installed on the system.
* Closes: #34094
