codegen: add Android NativeModule generator base structure

Summary: * Allow generate-native-modules-specs-cli.js to generate Android specific files * Add stub impl for Java spec generation (the output are still incomplete, see the next diffs for missing impl + tests) * Adjust the CLI to only produce modules stuffs, there's no need to produce components code Changelog: [Internal] Reviewed By: mdvacca Differential Revision: D22860936 fbshipit-source-id: 38aae390189f143f6c6216995437ac1ff15a1788
