Remove base/win/metro.{cc|h} and some associated code

The goal was to start by removing base/win/metro.{cc|h}, but this
ended up touching a number of places. So, also removed are:

chrome/browser/metro_utils/
chrome/browser/ui/apps/apps_metro_handler_win.{cc|h}
chrome/browser/ui/metro_pin_tab_helper_win.{cc|h}
chrome/browser/ui/views/frame/browser_frame_ashwin.{cc|h}

In order for the CL to not get even larger, there are some added TODOs
pointing at the associated bug where calls to the above were removed,
but the surrounding code is not yet simplified.

BUG=558054
