Use #import for ObjC headers

Done.

+#include "chrome/browser/media/desktop_media_picker.h"
+
+@class DesktopMediaPickerController;
+
+// Cocoa's DesktopMediaPicker implementation.
+class DesktopMediaPickerCocoa : public DesktopMediaPicker {
+ public:
+  DesktopMediaPickerCocoa();
+  virtual ~DesktopMediaPickerCocoa();
+
+  // Overridden from DesktopMediaPicker:

We usually have controllers owning themselves. How does this get torn down?

The Desktop Media Picker API will destroy the DesktopMediaPicker when the
callback is received or when the operation is cancelled (e.g. the app/extension
is closed). The latter is the main reason for ownership.
