[Mac] Don't unhide Chrome when a notification is displayed.

[Mac] Don't unhide Chrome when a notification is displayed.

Right now, if Chrome was hidden (cmd+h) and a notification comes in, the
whole app unhides.

Calling setHidden:YES on the notification window lets it be visible when
Chrome is hidden, and the -[NSWindow order*] methods respect it by not
unhiding the app.

[Mac] Don't unhide Chrome when a notification is displayed.

Setting the window to ignore the app's hidden state also stops Cocoa from
unhiding the app when the window is shown.
