product_config module will export productVariables struct (defined in android/variable.go). Other modules can depend on product_Config module to read product variables, without needing to update Soong. Bug: 346214955 Test: build and see output of product_config module Change-Id: I06e1d2716dc2a8b90984bb46c5fc901cd1ca5020
