We have plenty of completers which iterate over all values of
given enum and do nothing more than translate every member into
string (using corresponding virXXXTypeToString()).
Introduce a convenience function so that callers can pass just
VIR_XXX_LAST and virXXXTypeToString and the rest is taken care
of.
