RFR: 8088325 & 8169339 : Provide internal JDK API to JavaFX to locate JDK fonts

[Phil Race]

Hi,
Two bug ids, two webrevs and a cross-post since JDK needs to provide a
qualified export to JavaFX so it can access any fonts that may be provided
with the JDK.
FX bug: https://bugs.openjdk.java.net/browse/JDK-8088325
FX  fix : http://cr.openjdk.java.net/~prr/8088325/

JDK bug : https://bugs.openjdk.java.net/browse/JDK-8169339
JDK  fix : http://cr.openjdk.java.net/~prr/8169339/
