RFR [9] 8140687: Move @Contended to the jdk.internal.vm.annotation package

[Fabian Lange]

Hi Chris,

I was under the impression that making @Contended Part of Java SE was
planned for Java 9, but I might have been mistaken.
It is a very useful annotation and I am not aware of issues with it which
would justify removing it from public access.
We might not be voting on it, but I would lobby for continued support of
that feature.

Not sure if I would qualify it as critical. Its a different case. The JEP
260 APIs were there and always doomed to be removed. @Contended was placed
there intended to be promoted, right?
