  [Clang][Sema] Disallow applying `onwership_returns` to functions that return non-pointers (#99564)

`onwership_returns` works only with pointers, since it models
user-defined memory allocation functions. Make semantics more clear and
report an error if attribute is attached to wrong function.

Closes #99501
