Reland "Send dropEffect attribute on drag and drop events"

This is a reland of commit 0542983115c4ccbaa2b1dd15faff2675d520bbeb

Reason for reland: This CL was erroneously assigned blame for flakiness
in some tests Drag and Drop browser tests in chromeos and linux. See
bug: https://crbug.com/442927728

Original change's description:
> Send dropEffect attribute on drag and drop events
>
> This CL implements the dropEffect attribute in the dataTransfer property
> in drag and drop event to match the spec.
> https://html.spec.whatwg.org/multipage/dnd.html
>
> The attribute is currently not being set, defaulting to "none" on all
> events.
>
> Many existing tests were updated to pass with the new implementation.
> Notably, the default dropEffect for some "effectAllowed" attributes has
> been changed to match the defaults in the table found in "6.11.4 The
> DragEvent interface" in the spec. (defaulting to copy whenever copy is
> available, and to link if link is available)
>
