Set correct screenBounds for RemoteAnimation

Fix WindowContainer#getAnimationAdapter that creating
RemoteAnimationRecord set wrong parameter for screenBounds.

This can correct the position of split-screen task launching animation
that may shifted because the initial task view in launcher side is base
on screen coordinate.

Fix: 153581126
Test: manual as below steps:
     1) Launch a app, swipe up to overview screen.
     2) Tap app icon and pressing "Split screen" item.
     3) After entered split-screen mode, taps the task view.
     4) Make sure the secondary task animation the movement is
        correct and smoothly.
