[FSSDK-11823] ActivateListenerPaylod type fix in shared_types

[raju-opti]

Summary

• Currently, the notification payload types are exported from shared_types. But the current current types used in the notification center has diverged from these types, and these types are not used in the sdk. Therefore, the sdk user should not import/use these types either. But as these has been publicly released, we cannot change them in a incompatible manner either. So, updating these types as generic map to keep them backwards comptabile. Also exporting the actual payload types being used with new names. The user should use these new types instead.
