Check Flow and run basic packager tests using open source RN config
Summary:
Most of the changes associated with this commit will not be visible on GitHub, as they concern files in the internal Facebook monorepo. The bulk of this change is the addition of a new test that runs on the internal test infrastructure. The actual script used by the test has various references to the internal test infra, but a copy is produced below with some changes that should allow it to run on open source should anyone be interested in testing this outside of Facebook.
The test has the main goal of catching common sources of FB-to-GitHub breakages, such as the OSS Flow config falling out of date (we use a different flow config than what is synced out in .flowconfig, and hence internally we rename this file to .github.flowconfig). It also checks that the packager can run on a brand new project, among other things.
