Subject: [PATCH] Fix compilation on clang-21 / libc++-21 (#4477)
`<cstdlib>` was not being included, so malloc and free were only declared
via transitive includes. Some includes changed in the latest libc++-21
build which broke fmt.
Also changed `malloc`/`free` to `std::malloc` and `std::free`, as
putting those symbols in the global namespace is optional for the
implementation when including `<cstdlib>`.
