[libcxx-commits] [libcxx] [libcxx] Use __libcpp_verbose_abort for error messages (PR #108873)

LGTM, but please update your PR description to avoid mentioning that `__libcpp_verbose_abort` can be overridden. Indeed, we may want to remove that capability in the future (see e.g. https://releases.llvm.org/18.1.0/projects/libcxx/docs/ReleaseNotes.html#upcoming-deprecations-and-removals).

For embedded targets, I suspect that we'd want to instead provide a way to override how logging is done more generally, not just how to "log and abort".
