Fix memory leak with Freestyle renders after recent changes

Render stored a shallow copy of the scene view layers and views for thread
safety, without proper functions to free it. But with the CoW depsgraph this
scene is already a copy of the original and an additional copy is not needed.

Refactor to use the scene view layers and some other settings directly instead
of making a copy.
