Delete thumbTintColor, tintColor, onTintColor props

Summary:
Deprecations for these props were added in 0.57, June 2018, in this commit: 965adee#diff-6ee4e62c750fcd87064f152f53214a05, with warnings added in 9a4fd6b#diff-6ee4e62c750fcd87064f152f53214a05

It has been a couple releases now, so let's clean up the component code and finally remove support.

For instructions on how to migrate off these props, see the commit summary of 965adee#diff-6ee4e62c750fcd87064f152f53214a05
