Janic Duplessis 1af645b2fd Validate that JS and Native code versions match for RN releases
Summary:
Basic implementation of the proposal in #15271

Note that this should not affect facebook internally since they are not using OSS releases.

Points to consider:
- How strict should the version match be, right now I just match exact versions.
- Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help.
- Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning.
- Should the check and native modules be __DEV__ only?

**Test plan**
Tested that it works when version match and that it redscreens when versions don't before getting other errors on Android and iOS.
