This makes the code easier to follow and facilitates future refactoring, for example the set of known views can be removed entirely by making the clean up and navigation code use the stack of open views.
The SlidingPanelView class can thus be removed, saving various lines of code. The class implemented a small optimization for garbage collection, that was already less effective because various other objects are created during each view transition anyways.

The setMainView method of PanelMultiView controls the "mainview" attribute, which is already set or removed later in the showSubView method. When called at construction time, it changes the mainViewId if there is at least one child in the "panelmultiview" element and the original mainViewId does not already reference the first child. This would be incorrect, but in practice it never happens for either ephemeral or static panels, and can be avoided for the throw-away activated page action panel.
The setMainView method of PanelUI is never called, and this makes the corresponding PanelMultiView method removable.

The height of the subview being opened was supposedly calculated using an off-screen container independent from the currently displayed views, but this didn't work as expected because of the incorrect box alignment. This is now fixed and the correct minimum and maximum heights are set on the container separately, also preventing the current view from flickering before the transition in case the subview was taller.
With this issue fixed, the height can now be recalculated each time the subview is opened, without the caching that caused incorrect results when the same view was reopened with different elements or text.
Jumping could also occur because of a border applied only during the transition, which could influence the subview height in the presence of wrapping text.

* Let popup code initially measure and place the panel without maxHeight, this ensures alignmentPosition is a reasonable value
* Assign maxHeight from a popuppositioned handler and update the comment explaining the role of the autoPosition property
* Refactor to move the maxHeight calculation into a method on PMV
* panel autoPosition now gets reset to false in popuppositioned (was popupshowing) as the ShowWithPositionedEvent on popupFrame sets it back to true every time
* Update reflow tests with new signatures, and elimination of 1 reflow
* In appMenu reflow test, we must now wait for popupshown before opening subviews

The site security subview is now implemented using the "photonpanelmultiview" element, replacing the last instance of the "panelmultiview" element. The subview features a standard Photon header, hence the connection state icon was moved to the element below it. This makes the styles more similar between the main view and the subview. The connection state styles are now applied using a class name, and the tests have been updated accordingly.
This change required some fixes in the "photonpanelmultiview" implementation to make sure the height of the subview is correct and to allow keyboard navigation back to the main view.
Since the expander button and the permission controls in the main view are not visible anymore after the subview is shown, some code related to focus and hover could be removed as well.

* Harden the new `hideAllViewsExcept()` to not do erroneous things if called when
the binding is already gone.
* Generalize things into `hideAllViewsExcept(thisOne)`:
- Clear `_viewShowing` in there and do the descriptionHeightWorkaround thing
in there too,
- For Photon panels, do all the 'current' attribute setting in there. To show
a panel during transition, I introduced the 'in-transition' attribute.
* I had to make sure not to over-eagerly dispatch 'ViewShowing' events, because
that confuses some,
* Move the temporary panel handling, which contains an ephemeral panelmultiview
instance, internally. This cleans up the hacky, duplicate PanelUI.js code nicely.
* Keep a local copy of `_transitionDetails` to ensure it's still there after transition,
* Harden `_cleanupTransitionPhase()` to only clear the phase that belongs to a
specific transition, _if_ that's passed in as an argument. This resolves any
potential raciness that might occur when `showSubView()` is called again mid-transition.
* Skip the UITour element visibility check when it's inside a panelview, because
too many things need to happen and that check is too simple to be useful in
that case.

We weren't removing the 'open' attribute from the anchor if the transition didn't complete.
This patch fixes this by moving the addition of 'open' into _transitionViews, and its removal into
_cleanupTransitionPhase.

Prior to this change, showMainView set the 'current' attribute on a main view, but then _cleanupTransitionPhase() would remove it again.
This patch fixes that by calling showMainView *after* _cleanupTransitionPhase.
Separately, we weren't removing the 'open' attribute from the anchor if the transition didn't complete.
This patch fixes this by moving the addition of 'open' into _transitionViews, and its removal into
_cleanupTransitionPhase.
