Removing gtk2 support

[Kevin Rushforth]

I was thinking the same thing yesterday, but hadn't filed the issue yet. 
I just now filed:

https://bugs.openjdk.org/browse/JDK-8299595

If you are willing to do this, it would be appreciated. You can assign 
the bug to yourself. It will need a CSR and a release note.

My recommendation is that it be done without any refactoring of the 
sources, so that it is minimally intrusive. The changes would then be 
limited to removing the build task from build.gradle, and removing GTK 2 
as an option in "launcher.c" (leaving the logic in place in case we 
later want to support gtk4 and gtk3 in the same way we support gtk3 / 
gtk2 today).
