xen/console: introduce a 'w' debug-key that dumps the console ring

This patch adds a new 'w' debug-key, chosen from the limited remaining
keys only due to its proximity to 'q', that dumps the console ring to
configured console devices. It's useful to for tracking down how an
unresponsive system got into a broken state via serial console.
