Splitting from bug 891699.
https://chromium-review.googlesource.com/c/1277578 re-moved the cert viewer to be MacViews-based. We need to move the client cert selector to do the same thing, and then basically delete all these files:
"cocoa/single_web_contents_dialog_manager_cocoa.h",
"cocoa/single_web_contents_dialog_manager_cocoa.mm",
"cocoa/constrained_window/constrained_window_mac.h",
"cocoa/constrained_window/constrained_window_mac.mm",
"cocoa/constrained_window/constrained_window_sheet.h",
"cocoa/constrained_window/constrained_window_sheet_controller.h",
"cocoa/constrained_window/constrained_window_sheet_controller.mm",
"cocoa/constrained_window/constrained_window_sheet_info.h",
"cocoa/constrained_window/constrained_window_sheet_info.mm",
(in fact probably delete all of cocoa/constrained_window/*)
