[libvirt] [PATCH 5/7] Explicitly cast some switch parameters to enum

[Martin Kletzander]

This patch is not trying to fix every switch, just the ones I worked
with last time, because some of these were especially unreadable.
Covers enums virDomainGraphicsType and virDomainChrType (where
applicable).

Also sort it's cases by their value.
