Enhance Overflow menu to support responsive masthead design

[mcarrano]

We need enhancements to the Overflow menu component to support collapsing multiple dropdowns into a single menu as specified in the designs attached here: https://docs.google.com/document/d/1iN-FV-JsS1kial7wza7GG4Vu4jA0KfaXaxz5a0lrYcU/edit?usp=sharing

The Overflow menu component will allow any combination of actions or dropdown menus to be collapsed into a single drill-down menu when displayed on smaller viewposts. Implementation is needed to achieve our overall responsive masthead story.

@mcoker @mattnolting I believe we are still working on this as part of the masthead rework, correct?

@mcoker @mattnolting should this still remain open?

@mcoker @mattnolting Is this this pending?

@mcarrano @mattnolting This seems like a composable menu demo - rather than an OverflowMenu enhancement. Though there seem to be a couple proposed designs in the attached design doc. If we settle on one, we could build out a demo in an upcoming milestone?

There is a related design issue here: https://github.com/patternfly/patternfly-design/issues/1034 For the masthead, didn't we already solve this @mattnolting ? If so, I think we can close this.
