Enable the Cross-Version ABI diff configuration so developers can specify different flags for current and previous version ABI Check. The -target-version flag were added to determine the config section to be selected. The details of this configuration logic could be found in go/cross-version-abi-diff-configuration. Test: preform abi diff with config.json Bug: 239792343 Change-Id: I8fdad2d18096cfa7866183ecc2d7826682c85eb6
