[darwin] use new crash reporter api

Add support for the new crash reporter api if the headers are available. Falls back to the old API if they are not available. This change was based on /llvm/lib/Support/PrettyStackTrace.cpp

There is a lit for this behavior here: https://reviews.llvm.org/D96737 but is not included in this diff because it is potentially flaky.
