1. rowexec: fix oid handling in merge join and zigzag join …

   This commit is a follow up fix to
   a4b6234 which fixed how we handle zero
   value Oid types. In particular, we now need to have the precise type
   information for Oid type family to display zero Oid correctly.
   Previously, we could have imprecise information in merge join and zigzag
   joins that was stored in the right-hand side EncDatum when it was decoded
   using the LHS type, and this is now fixed. I don't think other join
   types (hash join and lookup join) are susceptible to this since they do
   decoding at different points in time, so it's unlikely we'd get
   a similar mix up there.
   
   There is no release note since it seems like an edge case (comparing Oid
   types with different Oids in non-default row-by-row engine).
   
   Release note: None
