Don't unconditionally create temporary render entities for visible objects. (#16723)
PR #15756 made us create temporary render entities for all visible
objects, even if they had no render world counterpart. This regressed
our `many_cubes` time from about 3.59 ms/frame to 4.66 ms/frame.

This commit changes that behavior to use `Entity::PLACEHOLDER` instead
of creating a temporary render entity. This improves our `many_cubes`
time from 5.66 ms/frame to 3.96 ms/frame, a 43% speedup.

I tested 3D, 2D gizmos, and UI and they seem to work.

See the following graph of `many_cubes` frame time (lower is better). PR
#15756 is the one in October.
