Upgrade to React Native 0.56

Implements zulip#2788

Upgrade dependencies, config and build files to RN 0.56

Previous upgrades were done manually by updating dependencies and
.flowconfig

This commit contains a full `diff` with previous versions.

What was done is:
 * run react-native-git-upgrade
 * resolve merge conflicts
 * update dependencies that were needed but missed by the script
