[roll] Roll fuchsia Revert "[debugger] Capture full stacks on some exceptions"

Original change's description:
> [debugger] Capture full stacks on some exceptions
>
> This changes exception handling in the backend to have different
> behavior depending on the type of exception we're handling. General
> exceptions (e.g. crashes, page faults, etc) now always send full stacks,
> which helps clients make decisions automatically.
>
> Also changed are software breakpoints exceptions that are not associated
> with any of our breakpoints. These can come from things like the gTest
> framework's assertion failures when running with
> --gtest_break_on_failure, for example, in addition to being manually
> typed by a developer.
>
> We want cases like these to already have a complete stack trace, when
> possible. In cases where unwind tables have been stripped from the
> debugged binary, we may not be able to make full progress with the
> synchronous target unwinder, and the client will have to do unwinding
> with the debug info on the host anyway, so this is best effort.
