Allow Overlay Display to take display flags

Browse Source 
Before, CTS test used WindowManager#shouldShowSystemDecors() to set show
system decorations after overlay display launched, which wouldn't enable
system decorations without relaunching. Now, we can set those flag
before display launch similar to what VirtualDisplayHelper does.
