* For #4844: add test cases for url elision
* For 4844: implement toShortUrl to pass test cases
* For 4844: update plumbing to use toShortUrl
* For 4844: adds/handles suggested url elision test case
Removed label from nav_graph that caused label to be set for each navigation
Removed title setting in onCreate() called for each navigation
Changed logic for checking current root when setting UI for normal mode
* For #4281: small ToolbarMenu refactor
This makes it easier to see how items are ordered in the menuItems list
* For 4281: add QAB buttons to menu
* For 4281: removed menu back button per mocks
I double checked with UX, and we'll be relying on the hardware back button for its functionality
* For 4281: add content descriptions for bookmarking
* For 4281: updated BrowserToolbarController for new functionality
* For 4281: provided simple dependencies to browser controller
More complex changes will be in a following commit, for review readability
* For 4281: move toolbar controller dependencies up to BaseBrowserFragment
The functionality they control is being moved into the toolbar menu, which is shared by both normal tabs and custom ones
* For 4281: removed (now unused) code related to QAB
* For 4281: fix test compilation after QAB removal
Tests still need to be expanded to include added functionality
* For 4281: updated menu to show if url is bookmarked
This sloppy workaround is required because TwoStateButton requires that `isInPrimaryState` be a synchronous call, and checking whether or not the current site is bookmarked is quite slow (10-50 MS, in my tests). After days of work and many attempted solutions, this was the least abhorrent among them.
https://github.com/mozilla-mobile/android-components/issues/4915 was opened against AC to evaluate potentially supporting async `isInPrimaryState` functions.
https://github.com/mozilla-mobile/fenix/issues/6370 was opened against Fenix to investigate the unexpectedly slow call to `BookmarkStorage`.
* For 4281: update reader mode switch
* For 4281: selectively show/hide menu items
* For 4281: add reader mode appearance
* For 4281: update bookmark button when it is clicked
* For 4281: removed unused QAB code
* For 4281: removed QAB robot, updated UI tests
* For 4281: removed QuickActionSheet metrics
Since this behavior now lives in the toolbar, it is tracked via Event.BrowserMenuItemTapped
* For 4281: fixed lint errors
* For 4281: add new strings for buttons added to menu
This is necessary because the location change (from QAB to toolbar menu) could affect the grammar in some languages
* For 4281: remove outdated TODOs
* For 4281: removed QAB container
* For 4281: removed back button reference from UI test
This button no longer exists
* For 4821: Fixes a visual defect (extra padding on top of toolbar)
* For 4281: update copy on reader mode
* For 4281: fixed review nits
