In our current implementation, we have multiple functions such as
`normalize_algoirthm_for_encrypt_or_decrypt` and
`normalize_algorithm_for_sign_or_verify` to normalize an algorithm, and
each of them works slightly differently. However, the spec defines a
single normalization procedure to handle all normalization.
This patch tries to consolidate our functions into a single
spec-compliant normalization function named `normalize_algorithm`.
The refactoring involves many existing code, so this patch only
introduces the new infrastructure without touching the existing. When
this patch gets approved and merged, we can then start migrating the
existing to the new infrastructure. (Note that SHA's digestion and
AES_CTR's encryption are also copied to the new infrastructure as
demonstration.)
More details about the refactoring can be found in the comment:

The Web Cryptography API has the "crypto task source"
(https://w3c.github.io/webcrypto/#dfn-crypto-task-source-0) to queue
tasks to resolve or reject promises created in response to calls to

This patch enables this task source at the script task manager, and
queue tasks on this task source from existing steps.
A few WPT error expectations are also added to WPT meta. The related

Regular shadow roots can never be detached once they are created.
However we were specifically detaching shadow roots from media elements
when they were disconnected. This is actually one of the very few
aspects of shadow roots that predate the implementation work I did
earlier this year.
I'm not sure why we ever did this. Maybe its for efficiency reasons,
because keeping the shadow tree around is not necessary when the media
element is not connected. But I can't imagine this yields any benefits,
especially since you would have to reconstruct the shadow tree when the
media element is re-connected (as is the case in the crash we observe).
For simplicities sake, I have completely removed this functionality.
Doing so ends up simplifying the code quite a bit.

The existing `assert!(node.is_connected())` is wrong. What it *wants* to
assert is that the style element has an owner, which is either a
Document or a ShadowRoot that the element is a descendant of. However,
if the element is descendant of a ShadowRoot which is itself not
connected to a document then the assertion would fail.
Instead, we use `node.is_in_a_document_tree() ||
node.is_in_a_shadow_tree()`, which more accurately reflects the intent.

Instead of having every single embedder implement keyboard scrolling,
handle it in script in the default key event handler. This allows
properly targeting the scroll events to their scroll containers as well
as appropriately sizing "page up" and "page down" scroll deltas.
This change means that when you use the keyboard to scroll, the focused
or most recently clicked `<iframe>` or overflow scroll container is
scrolled, rather than the main frame.
In addition, when a particular scroll frame is larger than its content
in the axis of the scroll, the scrolling operation is chained to
the parent (as in other browsers). One exception is for `<iframe>`s,
which will be implemented in a followup change.

Previously, when we click any element, it would trigger "scroll into
view". What's worse, for an anchor `<a>`, clicking it would "scroll into
view" instead of navigating to the url until you retry the click. The
reason is that we built `scrollIntoView` into the focus transaction
system with default option. However, the default `preventScroll` for
`FocusOption` is false according to spec, which triggers "scroll into
view" by default with focus triggered by interaction.
This PR
1. Adds spec document for those which really expects "scroll into view",
i.e. `<form>` when validating data.
2. Make sure when we begin focus transaction, we prevent "scroll into
view".
3. `Focus` method of element/document stays unchanged, which by default
scroll into view if no parameter provided according to spec.
Testing: Manually tested on `servo.org` and other websites, and examples
with `<form>` still correctly scroll into view when validation fails.

The signal taken from the requestinit is now passed into

This required implementing the algorithm to create
dependent signals, which is used in the `any()` method.
So that's now implemented as well.

In Step 15, we are given the unwrapped key as bytes. If the format is
"jwk", we execute parse-a-JWK algorithm to parse it (and deserialize it
to a JsonWebKey dictionary).
In next step, we perform the import key operation on the unwrapped key.
In our current implementation, we serialize the JsonWebKey dictionary
(when format is "jwk") back to bytes, in order to perform the import key
operation.
In fact, this serialization step is redundant since we have already been
given the unwrapped key as bytes in Step 15. We can directly use it for
perform the import key operation. This patch remove this redundant step
of re-serializing the JsonWebKey dictionary.
