Set additional bubble translation during stash

Fixes bubbles stash translation not getting cleared up after stash
animation finishes.

Bubbles are clipped using an outline animator during the stash
animation. They need separate translation applied to keep them within
the bounds of the bubble bar that is also shrinking and moving.

Set the translation for the bubbles in the stash controller so we can
reset the translation after the animation has finished.

Bug: 365829293
Flag: com.android.wm.shell.enable_bubble_bar
Test: TransientBubbleStashControllerTest
Test: have bubbles in bubble bar, trigger a new auto expanding bubble,
  check translation for bubbles
