Add types to scripts and config files (#1277)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1277

Now that we have some TypeScript infra set up, move scripts (mainly the benchmarking one) and config files to TypeScript.

Starts to move away a bit from the magic globals used in the JS environment.
