external_connection: Apply HAL ABI versioning

To support OS upgrade feature, hal-backend and hal-api module needs HAL ABI versioning.
So, major/minor version is added to hal_backend structure.
While applying HAL ABI versioning, hal_backend_[module]_funcs is allocated from hal-api-[module] side.
Thus, allocation is moved to hal-api-device-external_connection side.
