Improve the type of Platform.select for Android

Summary:
There's no need for the 3 type arguments here. Flow will infer a union already if multiple properties are provided. Worse, by not providing these properties these tvars end up with no bounds, which can cause downstream constraints to stall. All of the suppresisons added here are for legitimate errors that were uncovered by consolidating to one type argument.
