Fix Android comment and docblock typos

Summary:
👋 Hello! Thanks for react-native, it’s a great project.

I was digging into the Android implementation in _ReactAndroid_ and noticed a couple typos in the documentation. I went through and tried to fix all the typos I could find using [aspell](http://aspell.net).

Not applicable: these changes are only to comments, and CI should be skipped.
