Don't allow popups during page unload (removed)

Pages may not use the window.open() API to open a new page during its unload. The popup blocker already prohibited this, but now it is prohibited whether or not the popup blocker is enabled. This was originally targeted at Chrome 72, but moved to Chrome 74. For now, enterprises can use the AllowPopupsDuringPageUnload policy flag to allow popups during unload. We expect to remove this flag in Chrome 82.
