Add webkitTrustedOnly event listener option
https://bugs.webkit.org/show_bug.cgi?id=302977
rdar://165233141
Reviewed by Sihui Liu.
This adds a webkitTrustedOnly option to addEventListener, which is similar to
the wantsUntrusted
option supported by Gecko, except that Gecko's default for that option is
context-dependent
(e.g. depends on whether the event listener is in a browser chrome or page
context), whereas
webkitTrustedOnly always defaults to false (which seemed easier to reason about
and also seemed
important for backwards compatibility).
The option prevents event listeners from firing for untrusted events. Scripts
can already achieve a
similar effect with an early return if `!event.isTrusted`, but in some cases we
want to avoid even
that overhead.
Currently we only support this option in the autofill world.
