Depsgraph: Make Copy-on-Write a command line option

Before it was a compile time option which was not very easy to use or test. Now
the project is getting more mature, so very soon we will be able to call for a
public tests of limited features.

The copy-on-write (which includes animation, modifiers) is enabled using
--enable-copy-on-write command line argument.
