This change adds very basic support for tab navigation, but without
support for focus scopes. Followup changes will refine the behavior of
this implementation to follow the specification around focus scopes,
shadow DOM, and slots. In particular `delegatesFocus` is not supported
here yet.
Testing: This causes quite a few WPT tests to start passing.

Moves the `Drop` implementation for `GPUPipelineLayout` to a dedicated
private helper struct, `DroppableGPUPipelineLayout`. This ensures that
DOM types do not directly implement `Drop`, aligning with best practices
for resource management in the DOM. The associated `Bindings.conf` entry
is removed as direct `Drop` is no longer needed for this type.

This is a preparation for publishing to crates.io. Changes include:
- Add `servo-` prefixes to avoid name collisions on crates.io
- Use `-` instead of `_` in package names.
- Rename the crates to their original names in Cargo.toml,
to keep the diff minimal
- Rename `media` to `servo-media-thread` to avoid name collision with
`servo-media` (originally from the media repository).
This is an outcome of the previous discussion at [#general > Switch
remaining git dependencies to

`NormalizedAlgorithm::encrypt`, `NormalizedAlgorithm::decrypt` and other
similar functions have some catch-all `match` arms that are unreachable.
They are unreachable because we rely on the name attribute in `String`
of the subtle dictionaries and the `NormalizedAlgorithm` enum to
determine which cryptographic algorithm to use, while the algorithm
normalization mechanism guarantees that some combinations of name and
enum variants won't exist.
This patch tries to get rid of those unreachable `match` arms to make
our WebCrypto code more idiomatic so that the Rust compiler can help us
ensure the correctness in the future.
To achieve this, we break the enum `NormalizedAlgorithm` into multiple
enums: `EncryptAlgorithm`, `DecryptAlgorithm`, `SignAlgorithm`, etc.
Each one is associated to a cryptographic operation, and its variants
are the cryptographic algorithms that support the associated operation.
The inner type of each variant is the desired parameter dictionary.
Therefore, when the call `EncryptAlgorithm::encrypt`,
`DecryptAlgorithm::decrypt` and other similar functions, we can have
`match` statements that cover all patterns since those enums only
contains necessary variants.
To make this change, we also need to change the algorithm registration
mechanism. Instead of using the `SupportedAlgorithm` enum and its method
`SupportedAlgorithm::support` to register the operations of the
algorithms, the algorithm registration is now done in the function
`from_object_value` of a new trait named `NormalizedAlgorithm`, which
the new enums `EncryptAlgorithm`, `DecryptAlgorithm` and so implement.
(Note that the existing enum named `NormalizedAlgorithm` is removed.)
Some refactoring in also done in the `normalize_algorithm` function to
adapt the above changes.
This new design of algorithm registration is also closer to the
WebCrypto specification, as explained in the comment block below the
`normalize_algorithm` function.
The crate `strum` is also used to reduce some boilerplate code.
Testing: Refactoring. Existing tests suffice.

This fixes a crash on the attached testcase when running with the async
html parser enabled. The crash also triggers on wpt. When executing
parse ops received from the async parser, we were not considering the
case where one of these operations causes the parser to abort (in the
case above, said operation is the `<popup-info></popup-info>`).
```html
<body>
<script>
class PopupInfo extends HTMLElement {
connectedCallback() {
document.open();
}
}
customElements.define('popup-info', PopupInfo);
</script>
<popup-info></popup-info>
</body>
```
The bug is very obscure and only triggers if `document.open` is called
while there is no parser-blocking script **and** the document parser is
still active.

This PR fixes two related issues with Content Security Policy (CSP)

1. Missing nonce validation for external scripts with malformed

2. Incorrect violation event reporting for blocked external resources
This makes servo closer to passing the `nonce-enforce-blocked` wpt test.

2. Duplicate attrs check

```html

In the past, `ScrollEvent` is defined as a embedder's `InputEvent` and
being used only to forward the external scroll node id for a node that
is considered scrolled. This make us sends an additional message to
constellation and additionally, `ScrollEvent` went through lengthy
pipelines as it was deemed as an embedder input event, albeit being a
synthetic input fired by `WebviewRenderer`.
Subsequently, we could introduce a flag to detect whether the scrolling

Currently, `script` and `devtools` use a node's unique id to identify it
across requests. The unique ID is part of a node's rare data field and
is really only meant for debugging. Instantiating it on a node causes
it's memory usage to go up significantly. Now, when the devtools ask for
information about a specific `Node` then they send the unique ID to
`script`, and the script thread then walks the whole DOM tree searching
for that specific ID. This happens here:
6d0b651218/components/script/devtools.rs (L142-L153)
So, in the worst case, all of the nodes in the tree now have a unique
ID. That's not great!
Also, when `script` notifies `devtools` about changes to a DOM node then
`devtools` expects a `NodeActor` to exist for that Node. The actor might
not exist if the inspector doesn't know about that node yet - that
happens when the user hasn't expanded their parent yet.
That is an oversight from https://github.com/servo/servo/pull/42601 and
causes problems now(https://github.com/servo/servo/issues/42784) because
for the longest time, `devtools` was mostly the one sending requests. Of
course, we could make `devtools` simply ignore updates for nodes that it
doesn't know about, but ideally we shouldn't send these updates in the
first place.
This change implements a lookup map on the `ScriptThread` that contains
all nodes that have been sent to the devtools inspector. The map allows
us to efficiently resolve a unique ID to a `Node` in O(1), without
creating unique IDs for the whole tree. It also allows us to only send
DOM updates for nodes that the inspector cares about.
For now, entries from the cache are not evicted unless the relevant
pipeline is closed. That reflects reality, because the inspector also
keeps using them forever.
In the future we will tell the inspector when nodes are removed from the
tree - then it can't interact with them anymore, and we can remove them
from the script-side map.
This is change is not all that complicated but it involves moving a lot
of code around, so feel free to ask for clarification when something is
unclear!
