Subject: [PATCH] Updates shelf visibility from Launcher to SysUI

We used to set shelf visibility (and its height) from Launcher to WM and
with the PiP-SysUI migration, this function will be called from Launcher
to SysUI directly since SysUI will be the new source of truth for PiP
bounds.

Bug: 139016518
Test: atest PinnedStackTests
Test: Manual
