8167: Update flank-arm.yml with a device swap r=rpappalax a=AaronMT

For https://github.com/mozilla-mobile/android-components/issues/8150



The Pixel 2 (walleye) is a very constrained device, so the queue can build up and take a long time on Firebase. The Pixel 3 (blueline) and Pixel 4 (flame) have a lot more capacity and will likely run much faster. I'll swap this to the Pixel 3 as its using the same API as the Pixel 2.

7900: For mozilla-mobile/fenix#8765: Add site item widget r=gabrielluong a=NotWoods

`WidgetSiteItemView` is used to show a website inside bookmarks, history, collections, and other lists. Has the following API:
- `iconView` getter to load favicons into the view
- `setText(label, caption)` to set the text shown. If caption is null, the caption text view is hidden and the label is centered.
- `addIconOverlay` inserts other views above the `iconView`, such as a checkmark.
- `setSecondaryButton(icon, contentDescription, onClickListener)` will show an icon button with the given icon and content description. `onClickListener` is called when the button is clicked.
- `removeSecondaryButton` hides the button if it was previously shown by `setSecondaryButton`.
