New description:

 When you want to pass in a topogeom as a topoelement for building, the
 syntax is pretty ugly and hard to explain.

 As discussed in this thread
 https://lists.osgeo.org/pipermail/postgis-users/2023-February/045845.html

 In order to build hierarchical topoelement using topogeom, you need to do
 this ugly thing of


 {{{
 TopoElementArray_Agg(
 ARRAY[(topo).id,(topo).layer_id]::topology.topoelement )
 }}}

 It would be cleaner if we have a topoelementArray_agg that takes a
 topogeometry or have topogeometry be able to autocast to a topoelement.

 Then the above would reduce to

 TopoElementArray_Agg( topo )
