Use native bridge for animations

[dannycochran]

Motivation:
Rendering inconsistencies / slowness between screens in Android:
aksonov/react-native-router-flux#199
aksonov/react-native-router-flux#1177
aksonov/react-native-router-flux#1266

Fix
Basically patches in the change from https://github.com/facebook/react-native/pull/10289/files.

Once the above commit is merged into RN and pushed to a stable release, this can be merged. It won't be backwards compatible with older versions of RN, however.

I don't know how critical this fork is to the overall react-native-router-flux implementation, but long term it would probably be good to move off this fork altogether, or at least try to keep it up to date with the actual implementation of ExperimentalNavigation.

@aksonov would appreciate guidance here if you have thoughts?

Looks very good idea, unfortunately i can't test it, so maybe it is better to ask community to check?

[Kaishley]

@dannycochran Have the patches been merged yet in react-native?

[dannycochran]

@Kaishley no not yet, unfortunately. not sure why it's been in limbo so long.

I'll double check everything still works -- just FYI I've moved off of react-native-router-flux in favor of just using React Native Experimental Navigation. This forked dependency is significantly out of date and I'm not really sure what parts of it are modified compared to the actual implementation.

[dannycochran]

I just tested and this still works on RN 0.39.2.

@Kaishley @rossfishkind would you mind patching this change locally in your node_modules and confirming you see faster transitions while js debugging is enabled?

@dannycochran to what solution did u migrate? Was it an easy switch?

[dannycochran]

@K-Leon it's just a few changes:

Changing the NavigationAnimatedView.js with the code provided in this PR fixed slowness problem on my side.

Just applied and tested this PR for react-native-router-flux 3.38 with RN 0.43.3 and the animation slowness while enabling remote JS debugging is totally gone..
