Fix: Fluid/Cloth/DynamicPaint: Only share pointcaches in CoW case.
Particle copying code was already properly sharing pointcache between
orig data and its copy only when `LIB_ID_COPY_SET_COPIED_ON_WRITE` is
set, do the same for the other point cache users.
Using `LIB_ID_CREATE_NO_MAIN` here is waaaaaaay to much wide scope for
such a dangerous/advanced behavior, that kind of things has to be
strictly restricted in scope.
