Make all of new_/_like factory functions composite explicit autograd (#82238)
Once CompositeImplicitAutograd gets registered to Python key, this will
ensure that tensor subclasses can interpose on these functions directly
rather than getting decomposed. We prefer not decomposing as these
functions are functional, but their implementations use inplace
operations (and are thus more difficult to deal with, unless you use
functionalization.)
