Revert "Revert "Warn if PropType function is called manually (facebook#7132)""

This reverts commit be71f76.

In other words, now we again have the warning if you attempt to call PropTypes manually.
It was removed in facebook#8066 but we shouldn't have done this since we still want to avoid people accidentally calling them in production (and even more so since now it would throw).

Fixes facebook#8080.
