Subject: [PATCH] Add `data-disabled` to test fixtures (#1286)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1286

This can be marked in fixtures to skip a test without commenting it out. We add one more usage of this.

The same functionality existed (unused) before for `experiments`, which I changed to `data-experiments`.

Formatting of JS tests changed to be closer to what Prettier would output, and to remove usage of `Yoga.UNDEFINED` which doesn't existi and just resolves to `undefined` (this is converted to NaN by the wrapper layer).
