Merge bitcoin/bitcoin#28337: build: use Clang 15 for macOS cross-compilation

ff42d81 guix: use clang-toolchain-15 for macOS compilation (fanquake)
94955b4 depends: use LLVM/Clang 15.0.6 for macOS cross-compile (fanquake)

Pull request description:

  This will end up being a blocker for #28210, and is already part of #21778, even though an even newer LLVM/Clang combination is required (and still missing from upstream Guix). Seems straight-forward enough to just bump the macOS compiler to a more modern Clang.
