Move chooser_content_view from mac_sources to cocoa_sources

Fixes a MacViewsBrowser link error after r396494, starting at
http://go/macviewsbuilder/builds/10865, like

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_ConstrainedWindowButton", referenced from:
      objc-class-ref in libbrowser_ui.a(browser_ui.chooser_content_view.o)

chooser_content_view is the Cocoa UI. MacViewsBrowser gets its UI for
this from from chooser_bubble_ui_view.*
