Janic Duplessis f1a0695c7d Improve pointerEvents doc
Summary:The docs for touchEvents was really unclear and assumed that you know what `pointer-events` does in CSS. This is confusing especially for native developers, see [this issue](http://stackoverflow.com/questions/36068392/set-userinteractionenabled-false-in-react-native/36096413) on stack overflow.

I added a short description to the prop and all the possible enum values and made it so the comment that explain why it is a prop and not a style doesn't appear on the website as it is not really relevant there.

**Test plan (required)**
Tested by running the website locally.
Closes https://github.com/facebook/react-native/pull/6534
