  [orc] Reduce memory usage from empty materialization info DenseMaps (#88167)

Saves several MB of memory in larger applications after linking finishes
by clearing DenseMap storage that is empty. This does not attempt to
shrink partially full materialization infos. The assumption is that
adding more after linking finishes is rare.
