Pre-suppress errors for improved typing of `Array.{includes,indexOf,lastIndexOf}` in xplat

Summary:
In Flow 0.284, we will have a stricter version of `Array<T>.includes`. Instead of accepting `mixed`, we will only accept `T` to help catch logical errors. We did the same for `Array.indexOf` and `Array.lastIndexOf` as well.

This diff pre-suppresses newly discovered errors in part of the codebase.
