Softbody: unified copy functions
This unifies two almost-identical functions at the expense of having to add one single 'flag' value at one call. This makes copy_softbody() aware of the source/dest objects, allowing it to make a distinction between doing depsgraph evaluation copies and real object copies. This will be used in an upcoming commit to ensure that the pointcache is shared between CoW copies, similar to the current approach for rigidbody simulation.
