Add willShowImeOnTarget in RemoteAnimationTarget(Compat)

..used for signaling the launcher to crop the
remote animation target bounds when task animating on the taskbar.

If the task will show IME on the top means the animation taget would not
need to be cropped according to the taskBar insets, since visually the
taskbar is hidden when IME is visible.

Bug: 219981732
Test: manual as steps
 0) enable taskbar with Settings > Developer options > Smallest width
    as 600dp.
 1) launch an app from all apps and show the IME by tapping the editor.
 2) swipe out to home and launch it again by pressing the shortcut.
 3) Verify the animating task preview with IME shown without being
    cropped.
