bug#65007: [PATCH] Allow displaying program IO in the GDB buffer.

[StrawberryTea]

Yeah, I added `org-msg' and I have been trying to figure out how to send
a patch with it. Probably I would need to put it in a source block. But
I just turned that off

* lisp/progmodes/gdb-mi.el (gdb-split-io-flag): Don't create IO
buffer if `gdb-split-io-flag'.
(gdb-split-io-flag): New user option.
