add "aconfig_storage_reader_java" for generated flag lib

This change adds  "aconfig_storage_reader_java" for generated flag
library to read flag value from new storage.

Wifi module uses some aconfig flag for guarding the code. We are working switching the storage backend of the flag from DeviceConfig to a new storage system. The flag library will get the flag value though this reader library.

Wifi module added the flag library as source file, so we need to explicitly add the library here as a dynamic dependency for building purpose.
