Remove webkitdropzone.
webkitdropzone is a prefixed version of the dropzone HTML global
attribute. dropzone failed to gain traction among browser vendors, and
only Blink and WebKit implement prefixed versions. Therefore, dropzone
is being removed from the HTML specification in
https://github.com/whatwg/html/pull/2402
The following LayoutTests, which depended on webkitdropzone, have been
rewritten to use event listeners. These tests cover other drag-and-drop
functionality that we still want covered.
* fast/events/dropzone-001 -> fast/dnd/dropEffect-for-effectAllowed
* fast/events/dropzone-002 -> fast/dnd/dropEffect-for-image
* fast/events/dropzone-003 -> fast/dnd/dropEffect-for-link
* fast/events/dropzone-004 -> fast/dnd/dropEffect-for-file
The followng LayoutTests have been removed, because they do not cover
additional functionality that we still need.
* fast/events/dropzone-005 -> only covers dropzone-specific code
* fast/dnd/file-drop-on-webkitdropzone-element.html -> redundant with
fast/dnd/file-drag-drop-on-page.html
* http/tests/dnd/file-drop-on-webkitdropzone-element.html -> redundant with
fast/dnd/file-drag-drop-on-page.html
