gdbstub: Add Xfer:siginfo:read stub
Add stub to handle Xfer:siginfo:read packet query that requests the machine's siginfo data. This is used when GDB user executes 'print $_siginfo' and when the machine stops due to a signal, for instance, on SIGSEGV. The information in siginfo allows GDB to determiner further details on the signal, like the fault address/insn when the SIGSEGV is caught.
