i386/pc386: Add support for the gdb stub to use available console drivers.

Move the gdb stub from the i386 UART code to use the libchip drivers.

Use any ports discovered during the probes.

Add gdb control to the boot command line.

Change the device naming to the full device path, not a partial path.
For example /dev/com1.
