Launcher3: Disable live tile

Method as per Google commit 25399db1e7
("[DO NOT MERGE] Disable live tile in split mode for S").

Live tile has a LOT of bugs even in AOSP and Pixel stock ROMs:
* Alpha animation randomly not applying causing app to get stuck
* X/Y translation not applying causing app to get stuck
* Causes extreme jank (enable HWUI bars and swipe in recents...)
* Sidescroll tile minimization cuts off content instead of shrinking it.
* Screenshotting a sidescolled live tile causes it to become invisible.

Combined with our blur/transparency changes:
* The tile doesn't actually shrink because Google just draws background
  over the tile instead of shrinking it...
* The tile gets blurred which has to be fixed in very hacky ways,
  because it is on a very low layer, which is below the blur
...the end result is a total mess.
Kill this feature, and revisit fixing our issues once Google gets their
own shit together.
