Bug 1864838 - Update our Sanitizer to the new proposed WebIDL. r=emil…

…io,freddyb

The new proposed WebIDL is at WICG/sanitizer-api#181 (comment).
Sadly we don't have a real spec for this yet. Luckily this is mostly
just a renaming. The biggest change is that every <element> in elements: now has a list of allowed and removed attributes.
