RFR: JDK-8272375: Improve phrasing of synthesized descriptions in JavaFX docs

[Jonathan Gibbons]

Please review a very simple change to the support for the synthesized method descriptions in JavaFX. 

The change is just to change the order of words in generated descriptions from  
  _the property `NAME`_ 
to 
  _the `NAME` property_

As such, there are no changes to the mainstream code; just a change to the resource files and corresponding changes to some tests.
