Adds browser preferences to configure first-run flow on Windows 8.

- master_prefefrencs/installerdata file may now contain
  { "distribution": {
      "suppress_first_run_default_browser_prompt": true
    } } 
  to suppress the Win8+ first-run dialog that walks the
  user through making Chrome the default browser. 
  If the dialog is suppressed, the default browser
  butterbar/prompt appears on first run instead.

- master_preferences/installerdata file may now contain
  { "browser": {
    "suppress_switch_to_metro_mode_on_set_default": true
  } }
  to suppress switching to metro mode on Win8+ immediately
  after Chrome is made the default browser via the first-run
  dialog.

This CL also removes the non-dialog mode of 
SetAsDefaultBrowserUI and fixes a problem where the dialog 
would be shown only when master preferences were not given.


BUG=135255,135256,135257
TEST=Verify that modifiers described above act as 
advertised in setup procedure on Win8. If both prefs are 
absent, the program should show a modal set-default dialog
and upon successful change restart Chrome *into the
normal first-run flow* in Metro. Note that butter-bar set
default is not expected to restart into metro.
