Bug 1470510 - Rename nsXULWindow and nsIXULWindow to AppWindow and nsIAppWindow. r=smaug

nsXULWindow is no longer XUL specific and is somewhat confusing name.

Differential Revision: https://phabricator.services.mozilla.com/D51486

rename : xpfe/appshell/nsXULWindow.cpp => xpfe/appshell/AppWindow.cpp
rename : xpfe/appshell/nsXULWindow.h => xpfe/appshell/AppWindow.h
rename : xpfe/appshell/nsIXULWindow.idl => xpfe/appshell/nsIAppWindow.idl
