React-native needs to use project references in Typescript

[BethanyBerkowitz]

If we want to leverage Typescript Project References correctly, we would need to build the typescript files outside rollup.
See this #1078 for more information.

I started this, then decided it would be better to wait until #1097 is complete because I think @subzero10 is most likely going to make changes to the rollup config and I don't want to introduce conflicts. Also, he may strip out the spot where we import package.json, which would make messing with the build process easier (both typescript and rollup do not like the fact that we import a file that's above the src directory).
