Once the next round of JDK changes from the jigsaw/jake sandbox are integrated to the jdk9 mainline forest and in a promoted build of the JDK, we need to make changes in JavaFX to support the new module-info syntax.

These changes are already in a parallel src/main/jake directory for those modules that require these changes, so the fix will be:

1. Copy module-info.java from modules/*/src/main/jake to modules/*/src/main/java
2. Remove modules/*/src/main/jake
3. Remove the temporary build logic so that we no longer produce modules_src_jake

Since these changes not backward compatible, we will also need to update the minimum jdk-9 build number at the same time.
