Set exclude_kotlinc_generated_files to false explicitly since kotlin reflection is used in some Connectivity test cases kotlin code.

Property "exclude_kotlinc_generated_files" is recently added to exclude some kotlinc generated files that are not needed if kotlin reflection is not used. Currently it defaults to false since there are test failures(b/213966211) which is in FullScoreTest#testToString and FullScoreTest#testMinMaxPolicyConstants that uses kotlin reflection and fails if exclude_kotlinc_generated_files defaults to true. By setting explicitly exclude_kotlinc_generated_files to false on tests like FullScoreTest#testToString, we will be able to finally default this property to true so the kotlinc generated files can be removed for most modules that don't need them.
