For arm-compat, initialize console_{in,out}_gf;
otherwise, initialize stdio file descriptors.
This will go some way to cleaning up arm-compat, and

semihosting: Add GuestFDConsole
Add a GuestFDType for connecting to the semihosting console.
Hook up to read, write, isatty, and fstat syscalls.
Note that the arm-specific syscall flen cannot be applied
to the console, because the console is not a descriptor
exposed to the guest.
