What are the reasons/motivation for this change?

Explain how this is achieved.
Specify
llvm@20
in brewfile, and use the brewfile for macOS CI runs.Also add macos-latest to test-compile.
Note that setting macOS compilers to specify clang-19 passes C++17, but fails C++20 (on both x86 and arm) despite passing both C++ versions under ubuntu, spun out to #5320.
If applicable, please suggest to reviewers how they can test the change.
