Generic configuration for generic system modules.
Config object includes a copy of itself for the generic configuration.
The generic configuration replaces any product-specific configurations
with the generic information.
When a module context gets Config() object, it returns the generic
configuration if the module sets use_generic_config to true. Otherwise,
Config() returns the original config object as before.
By adding `generic:"<value>"` annotation to the product variable, the
variables will be initialized with the <value> for the generic configs.
If the <value> is "unset", the variable will be unset.
The generic modules can be included in the shared system image to be
installed in multiple targets.
