[11] RFR JDK-8202199 : Provide public, unsupported API for FX Swing interop

[Kevin Rushforth]

Thanks, Prasanta.

As an additional note to reviewers:

The JDK portion of this change (JDK-8202199) is the subject for this review.

The FX webrev is enough to be able to test the JDK side, but will need 
additional refactoring (to allow it to continue to build / run with JDK 
10) before being ready for review. If you spot something of concern in 
the FX webrev, please feel free to bring it up, but don't spend time 
doing a thorough review just yet.
