[Mac] Polish the search engine manager

* Make the edit search engine window a sheet.
* Only allow one instance of the search engine manager to be opened at once.
* The search engine manager now remembers its position.
* Create NSWindow(LocalStateAdditions) category to assist with storing window
  position in Chromium's local state.

BUG=21761,21762,21883,21996
TEST=Editing/adding a search engine happens in a sheet. Press [Manage] multiple times and only 1 window should open. Press [Manage] and the window should be at its last position.
