Added PRIVATE_FLAG_HIDE_NON_SYSTEM_OVERLAY_WINDOWS window flag.
When a window with this flag is visible, then any other window added
by an application process that requires OP_SYSTEM_ALERT_WINDOW
permission or that are of TYPE_TOAST will be hidden.
Bug: 62196835
Test: go/wm-smoke
Test: Added the new flag to the RecentsActivity onCreate, launched FB
chat heads and observed the head head become invisible when Recents is
visible and the chat head become visible when Recents is no longer
visible.
