Bug 1935687 [wpt PR 49568] - Expose attributionsrc support on <area> …

…through IDL, a=testonly

Automatic update from web-platform-tests
Expose attributionsrc support on <area> through IDL

This was already unintentionally supported due to the handling of the
attributionsrc attribute on HTMLAnchorBaseElement, and is reasonable to
support anyway, as <area> is a first-class navigation surface, just like
the already supported <a> and window.open.
