simplifier: Mark attribute and point simplifiers as stable

While both functions may see further behavior changes, they should be
consistent with the existing interface in terms of meaning of values,
and no interface changes are planned for these functions. New
functionality can be exposed either via the options bitmask or via new
functions.
