feat(PanelService): Left or right side panel to auto start as closed but auto open when needed (#3212)

* feat(SidePanel)
OHIF issue #3135
- Added a method to set a callback for a Panel to invoke when it is ready
to be shown (e.g. its data is loaded).
- Implemented such methods for both the segmentation and measurement panels.
- The SidePanel component now adds a callback to Panel components so that
it will automatically open a Panel that was initially closed and yet to
be opened.
- Updated the OHIF documentation accordingly.

* PR feedback
- added a PanelService that centralized much of the logic that existed in panel PanelModule
- the SidePanel subscribes to PanelService.EVENTS.ACTIVATE_PANEL for each of its child panels

* Removed the PanelMeasurementTableTracking setMeasurementPanelContentReadyCallback method.

* Made the forceActive flag in the PanelService optional and defaulted it to false.

* Fixed failing top level exports unit test.

* - PanelService subscriptions are now per panel (id) so subscribers do not
necessarily need to check the panel id in the event when it is fired
- PanelService activate panel trigger subscriptions are now returned
so that they can be (better) managed outside of the service
- updated/created the various documentation for panels and PanelService

* Clarified various documentation.
Moved the code to add the activate panel triggers out of the extensions
and into the longitudinal mode.

* Removed the openWhenPanelActivated flag.
PanelService now conforms to extending PubSubService like the other services.
Updated various documentation.

* Fixed failing e2e, mpr test.

* Renamed the ActivatePanelTriggers type properties.
The ExtensionManager now sets the id of various modules as a property on each of those modules.
