Support controlling interface and member visibility via preferences
This was easier to throw together than per-attribute/method support, and it gets rid of some nonstandard properties from our globals.
Fixes#7626.

Referer header
PR1 for https://github.com/servo/servo/issues/10311
This puts the code and data structures in place to set the Referer header based on the Referrer Policy for a given document. Note that document:: get_referrer_policy() always returns the 'No Referrer' option, so for now, this should have no impact on production code, and that policy requires that the Referer header is not added.
Later PRs will determine the policy and edit that get_referrer_policy() accordingly.

add pass-through from doc to http-loader for referrer_policy, ref_URL
add logic for setting referer header
add script pass-through for referrer
add unit tests for setting referer header
It's now set through the intermediate InterfaceConstructorBehavior structure,
which lets us improve the abstraction around NonCallbackInterfaceObjectClass
a bit better.
When the interface's constructor is supposed to always throw, the error for
calling `Foo()` without new is "Illegal constructor.". when the interface
actually defines an interface, the error is instead
"This constructor needs to be called with `new`.".
Fix typo: `cannot not outlive` -> `cannot outlive`
A `Root` cannot outlive the `RootCollection` it is recorded in.
The docs were saying otherwise.

Add API base url method to global objects
This adds an `api_base_url` function to global objects, which fixes `open-url-base.htm` under XMLHttpRequest.

This allows keeping the VertexAttrib* calls asynchronous.
Another option would be to do the validation in the apply() function,
but that'd require us passing an unnecessary channel around and add
extra synchronization.
The counterpart of this is that it has to be updated when the context
changes, but that's less problem.
Fixed compile error in generated code, when webidl constructors have same number of args
One of the ways that generated code differentiates constructors is by comparing if the args are array-like. The generated code was calling a function `IsArrayLike` that no longer exists. I re-implemented it with a more rust-like naming scheme.
