hw/xen: Move xenstore_store_pv_console_info to xen_console.c

Browse source 
There's no need for this to be in the Xen accel code, and as we want to
use the Xen console support with KVM-emulated Xen we'll want to have a
platform-agnostic version of it. Make it use GString to build up the
path while we're at it.
