CoreDumpSvc: Add StackTrace property

Add a boolean `StackTrace` property (default: `False`) that will create
a stack trace using ROOT's stack trace generator (usually invoking
`gdb`). This is useful for cases where there is no default signal handler
doing this, or if for some reason the signal handler is not usable
(ATR-20918). For a regular athena job this should not be necessary. If
used anyway, one should set `CallOlderHanlder = False` to avoid multiple
stack trace generations.
