Revert 98679 - Restoring a session should restore window minimization state on Windows

These changes enable save and restore of minimized window state on Windows.  (Mac and Linux came prior).  The window state is now saved whenever size-changed notifications fire (in addition to the original activation and close cases).

BUG=43274
TEST=Manual.  Launch Chrome on Windows, create two browser windows, minimize "a" window, quit.  Relaunch, expect "a" to be minimized.
