Add support for multi row select and context menu in Timegraph Component

changes made:
- Support for adding context menu via signals
- Support for making multiple selections in data tree of timegraph component
- Added Signals to notify context menu selection and multi row selections

This change will allow for a context menu to be added to the timegraph
component based on the outputDescriptor id via a signal. The component
also adds the ability to select multiple rows. The multi selections can
be passed with the item clicked signal payload as well as through a rowSelectionsChanged
signal. The end goal is to provide the timegraph views with the ability
to make multi-row selections and perform some actions with the selections.
