* Sometimes would cause an unending stream of accessibility events (particularly if starting off-screen). This would break TalkBack and anything that depends on UiAutomator (although the system itself took it like a champ).
* Sometimes would not load images (because the ViewTreeObserver would never fire onGlobalLayout after being added because measured width was 0, even though a new width was calculated later).
* Would not recalculate the number of icons that fit if the width changes after the first layout.
Combining ViewHolders with waiting for measuring and/or ViewTreeObservers was always a wonky approach, even though it should've worked in theory. This should be more robust.
Also fixes the unwanted animation on mode screen load related to the absence of the header name being applied a tad too late.

Switching from Priority Apps to None would still show the icons of the priority apps. There were several minor things wrong:
* We were keeping the AppSession when a mode switches from "priority apps" to "none", and because onResume always fires the callback, we were loading the icons.
* Even when deactivating the session, its own onResume lifecycle listener was still firing one extra time, before we had a chance to deactivate it.
Also two minor improvements to CircularIconsPreference:
* Update mLoadedIcons when we early exit due to mIconSet having no items. Mostly for testing, since the icons wouldn't be visible anyway.
* Use notifyChanged() when we get a measured view, instead of holding a reference to the view. Technically the previous code violated the "shouldn't keep references to views outside of onBindViewHolder" (although I didn't see this having an effect in practice).

Fixed view reuse. The views obtained from the ViewHolder should not be stored in Preference fields, since they can be rebound and thus a Preference can end up updating the wrong view.
Also added equivalence to the item class in the People segment so there is no flicker when the mode is reloaded.

Also set some alpha on the circles so that they look more or less disabled as well.

* Support comparing icon sets with a custom equivalence (needed because AppEntry doesn't implement equals(), and somewhat tricky because CircularIconPreference itself is not generic).
* Use final icons for allowed sounds.
* Use final appearance for +n icon.

(Some icons are temporary, until we get the final assets)
Also some fixes/improvements to CircularIconsPreference:
* Show the correct placeholder and +N icons.
* Fix the displayIcons-before-measure case (global layout listener was incorrect).
* Properly cancel pending image load futures (field didn't point to the actual future).
* Don't reload icons if it's the same set (depends on equals() for the items, so unfortunately doesn't work for AppEntry yet).
