Refactor ChooserBubbleUiController on Mac

This is part 2 of enabling the chooser UIs for Bluetooth from
Apps to enable developers to make a transition.

Since the chooser content view is the same for WebBluetooth on desktop
and Chrome Apps, it is better to pull it out of ChooserBubbleUiController
and have a class ChooserContentView that can be reused.

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.*
