Simply how `ProgressiveWebMetrics` works:
1. Keep only a single struct instead of one in layout and one script
that both implement the `ProgressiveWebMetrics` trait. Since layout
and script are the same thread these can now just be a single
`ProgressiveWebMetrics` struct stored in script.
2. Have the compositor be responsible for informing the Constellation
(which informs the ScripThread) about paint metrics. This makes
communication flow one way and removes one dependency between the
compositor and script (of two).
3. All units tests are moved into the `metrics` crate itself since there
is only one struct there now.

* Migrate to 2024 edition
Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>
* Allow unsafe_op_in_unsafe_fn lint
This lint warns by default in the 2024
edition, but is *way* too noisy for servo.
We might enable it in the future, but not now.

This change exposes a single `InputEvent` type and now there is only a
single delegate method for this `WebViewDelegate::notify_input_event`.
- Clipboard events are now handled as `EditingAction` inpute events. In
the future this can include things like "Select All", etc.
In addition, many parts of the dance to pass these events can now be
simplified due to this abstraction.
- All forwarded events are handled the same way in the `Constellation`,
though they may carry an optional hit test (for events that have a
`point`) which affects which `Pipeline` they are sent to.
- In the `ScriptThread` we now accept these `InputEvents` and use them
everywhere. Now all "compositor events" are "input events".
- This allows removing several data structures which are no longer
necessary.
- We no longer inform the embedder when an event was handled by a
WebView as that was only important for a MDI feature that will
no longer be so important the full-featured `WebView` API.

(#35226)
At some point in the past this message was only sent from the
`Constellation` to `script`, but nowadays this is sent from various
parts of servo to the `ScriptThread`, so this is a better name. In
particular, the current name makes it seeem like this message controls
the `Constellation`, which it does not.

Instead of setting up a route for every image load in the DOM / Layout,
route all incoming image cache responses through the `ScriptThread`.
This avoids creating a set of file descriptor for every image that is
loaded.
This change requires having the `ImageCache` track the `PipelineId` of
the original the listener so that the `ScriptThread` can route it
properly to the correct `Window`.

This allows reusing the asynchrnous fetch mechanism that we use for page
resources and is likely a step toward removing the `FetchThread`.
Benefits:
- Reduces IPC traffic during navigation. Now instead of bouncing
between the constellation and the `ScriptThread` responses are sent
directly to the `ScriptThread`.
- Allows cancelling loads after redirects, which was not possible
before.
There is the question of what to do when a redirect is cross-origin
(#23037). This currently isn't handled properly as the `Constellation`
sends data to the same `Pipeline` that initiated the load. This change
doesn't fix this issue, but does make it more possible for the
`ScriptThread` to shut down the pipeline and ask the `Constellation` to
replace it with a new one.

Previously, senders and receivers to different kinds of event loops (the
main `ScriptThread`, different types of workers) used a rust `trait`
mechanism to implement dynamic behavior. This led to having many unused
implementations of this `trait`. This change moves to using an `enum`
based approach for these senders and receivers and removes all of the
dead code.
In addition, to allowing for use of rust's dead code detection, it
simplifies the code a great deal. All of these generic senders and
receivers are moved to the `messaging.rs` file and given proper
documentation.
Finally, empty an `JSTraceable` implementation is made for all
crossbeam `Sender<...>`s to avoid having to manually skip them everytime
they are included in structs. The pre-existing empty `MallocSizeOf`
implementation is used more thoroughly.
Other unecessary wrappers around these senders and receivers are removed
as well.

Instead of creating a type for each `TaskSource` variety have each `TaskSource`
hold the same kind of sender (this was inconsistent before, but each
sender was effectively the same trait object), a pipeline, and a
`TaskSourceName`. This elminates the need to reimplement the same
queuing code for every task source.
In addition, have workers hold their own `TaskManager`. This allows just
exposing the manager on the `GlobalScope`. Currently the `TaskCanceller`
is different, but this will also be eliminated in a followup change.
This is a the first step toward having a shared set of `Sender`s on
`GlobalScope`.

Create two new data structures in the `script` crate to hold senders and
receiver:
- `ScriptThreadSenders`: holds all outgoing channels from the
`ScriptThread` including a channel to the `ScriptThread` itself. The
ultimate goal with this is to reduce duplication by giving a boxed
version of this this to `Window`s.
- `ScriptThradReceivers`: holds all incoming channels to the
`ScriptThread`. This isn't cloenable like the senders. This is used to
abstract away `recv()` and `try_recv()` methods used to make the
`ScriptThread` event loop easier to read.
In addition:
- The many duplicated `ScriptThread` self-senders for the `TaskManager`
have been removed and, in general, a lot of boilerplate is removed as
well.
- Visibilty of all methods affected by this change is changed to
`pub(crate)` in order to take advantage of dead code detection. Some
dead code produced from macros is removed.
- Some conversion code is refactord into implementations of the `From`
trait.
- The names of channels uses a standard "sender" and "receiver" naming
as well as trying to be descriptive of where they go in `ScriptThread`
as well as `InitialScriptState`
