Translate the dot to correct position

- Pipes the dotCenter location through to BubbleFlyoutView
- Uses the dotCenter location to animate the flyout so that the location
  doesn't jump positions
- Updates the size that BubbleIconFactory uses to be the bitmap size
  rather than bubble size (this makes the badges look closer to launcher
  sizing)

Test: atest SystemUITests
Test: manual 1) have no bubbles, post a bubble, observe flyout animation
             2) move stack to opposite side, post a bubble, observe
	        flyout animation
	     Repeat above with the different icon shapes
