RFR: 8243115: Spurious invalidations due to bug in IntegerBinding and other classes [v2]

[John Hendrikx]

> This fixes a bug where the first call to unbind would clear the internal invalidation listener used, resulting in subsequent unbind calls to be no-ops, unless bind was called again first.
> 
> I had to rewrite the parameterized test slightly as Parameterized will only call the parameters method once, and my new test modifies the internal state of the bindings used as parameters (by doing some unbind calls) which was making other tests fail.

John Hendrikx has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains two additional commits since the last revision:

 - Merge branch 'master' of https://git.openjdk.org/jfx into feature/unbind
 - 8243115: Unregister bindings when unbind called multiple times
   
   This fixes a bug where the first call to unbind would clear the internal invalidation listener used, resulting in subsequent unbind calls to be no-ops, unless bind was called again first.
