[11] RFR JDK-8198249: Remove deprecated Runtime::runFinalizersOnExit and System::runFinalizersOnExit

[mandy chung]

Runtime.runFinalizersOnExit has been deprecated since 1.2 (1998)
and deprecated for removal in JDK 9.  We analyzed the maven central
artifacts few years ago that show very few uses of it.  I also
survey a recent version of most of the maven artifacts that references
runFinalizatsOnExit no longer references it.  I propose to remove
Runtime.runFinalizersOnExit and System.runFinalizersOnExit methods
in JDK 11.
