Can you split off this into its own interface?

clipboard.mojom:

module arc;

interface ClipboardHost {
  // Called when the Android clipboard content is changed. This is
  // typically fired when a user initiates a "Copy" action.
  // |text| is the text being set in the Android Clipboard.
  OnSetClipboardContent(string text);

  // Called when the Android clipboard decides to update its content.
  // This is triggered when a "Paste" action is fired or an app
  // or a service tries to retrieve the Android clipboard content.
  OnGetClipboardContent();
};


interface ClipboardInstance {
  Init(ClipboardHost host_ptr);

  // Sends the Chrome clipboard content to Android.
  // |text| is the clipboard content being sent.
  SendClipboardContentToAndroid(string text);
};

See https://codereview.chromium.org/1523643002/ for reference and further
examples.

Will do once crrev.com/1541653002 is relanded.

Will this only ever support text? Is copy/pasting other types of content a
non-goal? Will that use the same methods with changed parameters or will
additional methods be used to support that?

Btw, please use OnClipboardInstanceReady@109.
