iOS: Introduce spellCheck prop to TextInput

Browse Source 
Summary:
This exposes iOS's spellCheckingType functionality to JavaScript. The native functionality is a three state enum. It gets exposed to JavaScript as a boolean. The initial value and JS null map to the third state.

An alternative design for this API would have been to expose a three state enum to JavaScript:
  - "on" which maps to UITextSpellCheckingTypeYes
  - "off" which maps to UITextSpellCheckingTypeNo
  - "auto" (default) which maps to UITextSpellCheckingTypeDefault

For consistency, I decided to use the same API design as spellCheck. We don't have many options for fixing spellCheck in #11055 without introducing a breaking change.

**Test plan (required)**

Verified that switching `spellCheck` between `true`, `false`, and `null` all work correctly in single line and multiline `TextInputs`.
