Both Element's and ShadowRoot's setHTMLUnsafe, and Document's static
parseHTMLUnsafe methods are implemented.
(cherry picked from commit ce8d3d17c4f2fcca8fac0ff4a832c8f50a011fc7)
This stuff has moved from a mixin defined by the DOM Parsing spec, over
to the HTML spec, where they are now defined as partial interfaces for
Element and ShadowRoot.
There's also some new functionality that we don't implement yet, so
patch marks them as FIXME properties.
(cherry picked from commit 0c47b3ff971437c4bd3923134d26ad086b5f6a75)
NewAKString is effectively the default for any new IDL interface, so
let's mark this as the default behavior. It also makes it much easier to
figure out whatever interfaces are still left to port over to new AK
String.
The intent is to use these to autogenerate prototype declarations for
Window and WorkerGlobalScope classes.
And the spec links are just nice to have :^)
