Tyler Veness af7d68e993 [wpiutil] Use C++23 stacktrace library on Windows (#6839)
This lets us remove the unmaintained StackWalker library and its hacky
upstream_utils script.

@Gold856 reported that StackWalker gives blank stacktraces:

They also reported an earlier version of this PR giving the following
stacktrace instead:
