c14ba73a - [libc++] Define behaviour for calling target() and target_type() on -fno-rtti std::functions (#209471)

[libc++] Define behaviour for calling target() and target_type() on -fno-rtti std::functions (#209471) The main aim of this change is to have the same vtable between `-fno-rtti` and `-frtti`. Since it's very cheap to do, this also asserts if the `function` object was created in `-fno-rtti` mode. The vtable can be extended, since the members are either never accessed in `-fno-rtti` mode, or are already expected to exist in `-frtti` mode. This means that we either define behaviour that wasn't before, or we add some extra bytes that are never accessed.
