New first run sequence for Windows, with no UI. Organic builds will display the Search Engine Dialog, otherwise search engine is set to Google or silently imported, depending on master_preferences. (see go/chromefirstrun for details).
I also removed a no-longer-used SearchSelectObserver from FirstRunSearchView.
BUG=42612
TEST=First run import works as intended (see go/chromefirstrun). master_preferences file can still turn off import of history, search engine, and home page.
