vl: drop display_type variable 

Switch over all leftover users to qapi DisplayType.
Then delete the unused display_type variable.

Add 'default' DisplayType, which isn't an actual display type but
a placeholder for "user didn't specify a display".  It will be replaced
by the DisplayType actually used, which in turn depends on the
DisplayTypes availabel in the particular build.
