The signal taken from the requestinit is now passed into
the request object with the relevant steps. I added all
spec comments to this method, as I had trouble figuring
out which steps I had to add.
This required implementing the algorithm to create
dependent signals, which is used in the `any()` method.
So that's now implemented as well.
All of that required the machinery to have dependent and
source signals on an AbortSignal. It uses an IndexSet
as the spec requires it to be an ordered set.

The [idl interface](https://dom.spec.whatwg.org/#interface-customevent) and servo's implementation had diverged.
* Extra arguments to initCustomEvent are optional (fixes `dom/events/CustomEvent.html`)
* The CustomEvent constructor is infallible
* "[Exposed=*]" (and the same for the "Event" interface since it's
CustomEvent's parent.)

Most tests were only being run for layout-2013, not for layout-2020.
This wasn't great since layout-2020 is now the default.
So this patch unifies the lists of included tests for both layouts.
For layout-2013 this implies adding css/css-content/, css/css-logical/
and css/css-masking/clip/.
For layout-2020 this implies adding several additional css tests, and
also tests like dom/, js/, html/, etc.
