Some improvement of validation message bubble UI.

* Change anchor position arguments of some functions from the screen
  coordinate system to the root view coordinate system.  Blink can't
  provide a rectangle in the screen coordinate on Android, and we'd like
  to make it consistent. Each of validation message UI implementation
  converts the anchor postion to the screen coordinate.

* Support WebValidationMessageClient::moveValidationMessage.
  Add functions to ValidationMessageAgent, ValidationmessageFilter, and
  ValidationMessageBubble classes, and add new IPC message to
  validation_message_messages.h.

Changs for platform-specific files:
* chrome/browser/ui/android/:
  Just rename argument names; anchor_in_screen -> anchor_in_root_view
* chrome/browser/ui/cocoa/:
  Implement SetPositionRelativeToAnchor, add a helper function
* chrome/browser/ui/gtk/:
  Add BubbleGtk::SetPositionRelativeToAnchor, and use it for
  ValidationMessageBubble::SetPositionRelativeToAnchor implementation
* chrome/browser/ui/views/:
  Add SetPositionRelativeToAnchor implementation.
  Also, fixes a bug that ValidationMessageBubbleDelegate is never
  destructed because Hide() won't call DeleteDelegate. We should call
  Close().
