Adds the ability to disable entries in GR-DROPDOWN via the `disabledIds` property. GR-CHANGE-ACTIONS uses this to disable overflow menu change actions in the same way that it disables the buttons for top-level actions. Tests are added for both elements. Bug: Issue 5366 Change-Id: Iaeba5f5cb9cfa4d7a89d955a65f3a4134780942a
