LibCoreDump+CrashDaemon: Add and use CoreDump::Backtrace

Browse source 
Creating a backtrace from a crashdump already existed as a few
standalone functions in CrashDaemon. This patch refactors the code
required for this to make it generally usable and moves it to
CoreDump::Backtrace, which provides both raw data as well as
stringification.
