ozone/wayland: dnd: Support dragging to/from non-toplevel windows

So far, only WaylandToplevelWindow supports drag'n'drop, by implementing
ui::WmDragHandler, which prevents, for example, Chrome's Bookmarks DND
features from working as expected. Dragging a bookmark from the bookmark
bar into a folder makes the folder content to be shown in a popup/menu
window, which must get notified about the drag/drop events so the menu
controller can determine when to open/close menu items accordingly.

This CL address it by moving WmDragHandler impl to WaylandWindow base
class. Also, unit tests are added to make sure the DND events are
properly propagated to drag/drop handlers attached to non-toplevel
windows.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
