Cleanup: Remove redundant use of evaluated non-mesh objects

Metaball, curve, text, and surface objects use the geometry component
system to add evaluated mesh object instances to the dependency graph
"for render engine" iterator. Therefore it is unnecessary to process
those object types in these loops-- it would either be redundant work
or a no-op.
