Fixup TypeScript with export maps (#1284)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1284

This makes TypeScript resolution play nicely with export maps, and converts the entrypoints to TypeScript.

We remove the non-export-map fallbacks as well, so the export maps are always followed.

Tests are moved to load yoga from its external export, testing the entrypoints.

This moves the only untyped bit to the binary wrapper, which another diff will move.
