Switch favorites screen to grid layout

* Add logic to PhoneFavoritesTileAdapter so that it now supports an
unlimited number of tiled rows.
* Tiles now have a configurable height to width ratio.
* Fix animations so that tiles moving up and down rows appear to animate
in from the correct direction. Tiles moving to the row above should animate
in from right to left. Tiles moving to the row below should animate in from
left to right.
* Update the number of columns in the grid to 2.
* Update layout of individual tiles to match redlines from UX.
    * Tweak font sizes for tiles
    * No longer truncate names in tiles
    * Tiles have a 2-3 height to width ratio
    * Update assets and layout for favorite and more info icons
    * Add content description for the favorite button
* Add tests for PhoneFavoritesTileAdapter
