Add an additional layer of inheritance for `aosp_ripcurrentpro`, and
`aosp_ripcurrentpro_fullmte`.
This change adds a common layer of inheritance for non-factory
products (ripcurrentpro_generic.mk). This makes it easier to configure
factory and non-factory products differently.
Non-factory `ripcurrentpro` products now inherits from
`device/google/caimito/ripcurrentpro_generic.mk` which inherit from
`device/google/caimito/device-ripcurrentpro.mk`.
