win: Move autodel to C only

Note: this is C only, not legacy only.
The problem is that bindings will hold a strong reference to the window,
which will then die "under the rug" if autodel is enabled. This then
leads to at least ERR if not crashes.

Note:
elm_policy needs to support autodel and quit on last del only for C
applications. Bindings will require some other mechanism that doesn't
break all assumptions wrt. references.
