This change makes the devtools inspector show any event listeners that
are attached to a node. The primary motivation is making the devtools
more useful for debugging real-world websites.

You can also click on the event listener to show some more info, though
most of that (everything except the event type and the event phase) is
currently just placeholder text:

There were some `#[serde(untagged)]` and `#[serde(skip*)]` annotations
in the shared devtools types. These are needed for correct JSON
serialization when sending messages to Firefox, but they fail in
multiprocess mode since we are sharing them through the IPC channel with
bincode, which doesn't support certain serde tags.
The workaround is to keep all shared types free from problematic
annotations, and defining wrapping types that are only used in the
devtools crate.
One instance are console messages and page errors. They have been moved
to `console.rs`, with `shared/devtools` only keeping the parts that are
needed for communication between threads.
The other instance are auto margins. Now the final message is built in
`page_style.rs`.
Apologies since both of them were introduced by me, I wasn't aware that
we were limited by bincode in multiprocess mode. A warning has been
added to `shared/devtools` listing the problematic annotations that
shouldn't be used in this file.
Testing: `mach test-devtools` and manual testing using `--multiprocess`.

Fix a panic when calling `determine_auto_margins` for nodes without
`.style()`. Now it returns an empty `AutoMargins` (all options set to
`None`), which matches the behaviour in Firefox:
```json
"autoMargins": {}
"autoMargins": {"top": "auto", "bottom": "auto", "left": "auto", "right": "auto"}
```
Refactor `GetLayoutReply` and `ComputedNodeLayout` to take advantage of
serde's flatten feature, making the serialization much cleaner.
Testing: Manual testing with the example provided in the issue.

This implements LazyDOMString (from now on DOMString) as outlined in
https://github.com/servo/servo/issues/39479.
Constructing from a *mut JSString we keep the in a
RootedTraceableBox<Heap<*mut JSString>> and transform
the string into a rust string if necessary via the `make_rust_string`
method.
Methods used in script are implemented on this string. Currently we
transform the string at all times.
But in the future more efficient implementations are possible.
We implement the safety critical sections in a separate module
DOMStringInner which allows simple constructors, `make_rust_string` and
the `bytes` method.
This method returns the new type `EncodedBytes` which contains the
reference to the underlying string in either format.
Testing: WPT tests still seem to work, so this should test this
functionality.

to use the [SpiderMonkey Debugger
API](https://firefox-source-docs.mozilla.org/js/Debugger/) as the single
source of truth about scripts and their sources for devtools purposes
(servo/servo#38334), the debugger script needs to be able to distinguish
inline scripts from other scripts, because inline scripts are a special
case where the source contents need to come from the Servo parser.
the mechanism for this is
[Debugger.Script.prototype.**introductionType**](https://firefox-source-docs.mozilla.org/js/Debugger/Debugger.Source.html#introductiontype),
which is `inlineScript` for inline scripts or a variety of other values
for other kinds of scripts, but only the embedder can provide this
information.
this patch bumps mozjs to servo/mozjs#603, which expands on
CompileOptionsWrapper, making it a safe wrapper around CompileOptions.
to construct one from safe code, use Runtime::new_compile_options().
then you can call `set_introduction_type(&'static CStr)` on the new
instance. we also make Runtime::evaluate_script() take a
CompileOptionsWrapper from the caller, instead of constructing one
internally.
in this patch, we set the introductionType to `c"inlineScript"` when
calling run_a_classic_script() and compile_module_script() for inline
scripts, and leave it unset all other cases.
Testing: will undergo automated tests in #38334

Instead of running "update the rendering" at every IPC message, only run
it when a timeout has occured in script. In addition, avoid updating the
rendering if a rendering update isn't necessary. This should greatly
reduce the amount of processing that has to happen in script.
Because we are running many fewer calls to "update the rendering" it is
reasonable now to ensure that these always work the same way. In
particular, we always run rAF and update the animation timeline when
updating the ernder
In addition, pull the following things out of reflow:
- Code dealing with informing the Constellation that a Pipeline has
become Idle when waiting for a screenshot.
- Detecting when it is time to fulfill the `document.fonts.ready`
promise.
The latter means that reflow can never cause a garbage collection,
making timing of reflows more consistent and simplifying many callsites
that need to do script queries.
Followup changes will seek to simplify the way that ScriptThread-driven
animation timeouts happen even simpler.
Testing: In general, this should not change testable behavior so much,
though it
does seem to fix one test. The main improvement here should be that
the ScriptThread does less work.

This changes fixes two issues:
1. A reflow of all `Document`s currently done unconditionally after
receving IPC messages in the `ScriptThread`. Reflowing without first
updating the animation timeline can lead to transitions finshing as
soon as they start (because it looks like time advancement is
measaured between calls to `update-the-rendering`).
2. Fix an issue where not all `Pipeline`s were updated during *update
the rendering*. The previous code only took into account top level
frames and their children. It's not guaranteed that a particular
`ScriptThread` is managing any top level frames, depending on the
origens of those frames. We should update the rendering of those
non-top-level iframes regardless.
The new code attempts to order the frames according to the
specification as much as possible without knowing the entire frame
tree, without skipping any documents managed by the `ScriptThread` in
question.
In addition, `Documents` is pulled out the `script_thread.rs` and
renamed to `DocumentCollection`.

For a long time, `gfx_traits` has held a lot of things unrelated to graphics
and also unrelated to the `gfx` crate (which is mostly about fonts).
This is a cleanup which does a few things:
1. Move non `gfx` crate things out of `gfx_traits`. This is important in
order to prevent dependency cycles with a different integration between
layout, script, and fonts.
2. Rename the `msg` crate to `base`. It didn't really contain anything
to do with messages and instead mostly holds ids, which are used
across many different crates in Servo. This new crate will hold the
*rare* data types that are widely used.
Details:
- All BackgroundHangMonitor-related things from base to a new
`background_hang_monitor_api` crate.
- Moved `TraversalDirection` to `script_traits`
- Moved `Epoch`-related things from `gfx_traits` to `base`.
- Moved `PrintTree` to base. This should be widely useful in Servo.
- Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it
to `WebRenderFontApi`.
