Store the tuple conversion map to convert a tuple from a child table's format to the root format in a new ri_ChildToRootMap field in ResultRelInfo. It is initialized if transition tuple capture for FOR STATEMENT triggers or INSERT tuple routing on a partitioned table is needed. Previously, ModifyTable kept the maps in the per-subplan ModifyTableState->mt_per_subplan_tupconv_maps array, or when tuple routing was used, in ResultRelInfo->ri_Partitioninfo->pi_PartitionToRootMap. The new field replaces both of those. Now that the child-to-root tuple conversion map is always available in ResultRelInfo (when needed), remove the TransitionCaptureState.tcs_map field. The callers of Exec*Trigger() functions no longer need to set or save it, which is much less confusing and bug-prone. Also, as a future optimization, this will allow us to delay creating the map for a given result relation until the relation is actually processed during execution.
