Refactor the memory profiler code to return the struct. (#37155)
Refactor the memory profiler code to return the struct and handle the
serializing in servointernal page.
This allows other users of the memory profiler to see the whole report
without parsing json.

Testing: I do not know if the memory page is covered by tests.

Various memory measurement improvements (#36834)
The two significant changes here are 1) a commit that frees memory used
to perform memory reporting once the reporting is complete, 2) memory
reporting for the system font service. There are various other commits
that remove `#[ignore_malloc_size_of]` attributes for data that we are
now able to measure, but they do not significantly change our
measurements when testing servo.org.

Testing: Comparing the output of about:memory on servo.org.

Refactor common infrastructure for creating memory reports. (#36579)
This removes a bunch of duplicated code needed to support
ConditionalMallocSizeOf correctly, and fixes multiple places where that
code was subtly wrong (the seen pointers hashset was never cleared).

Testing: Measuring https://www.nist.gov/image-gallery lots of times.

compositing: Add memory reporter for WebRender. (#36557)
This adds a memory reporter for WebRender's memory usage. I seeded it
with a couple entries that looked reasonable based on
https://searchfox.org/mozilla-central/rev/2c71f1e9b5947612abdc16b64008162c58c1b9d3/gfx/thebes/gfxPlatform.cpp#722-738.

Testing: Verified that new numbers appear in about:memory for servo.org.
The new images category is surprisingly large (40mb).

Make the memory reporting multi-process aware (#35863)
So far the memory reporter aggregates reports from all processes, and
runs the system reporter only in the main process. Instead it is
desirable to have per-process reports. We do so by:
- creating a ProcessReports struct that holds includes the pid in
addition to the reports themselves.
- running the system memory reporter also in content processes.
- updating the about:memory page to create one report per process, and
add useful information like the pid and the urls loaded in a given
process.

Add an about:memory page (#35728)
This patch exposes a servo internal DOM API that is only made available to about:
pages on the navigator object to request memory reports. The about:memory page itself is
loaded like other html resources (eg. bad cert, net error) and makes use of this new API.

On the implementation side, notable changes:
- components/script/routed_promise.rs abstracts the setup used to fulfill a promise when the
  work needs to be routed through the constellation. The goal is to migrate other similar
  promise APIs in followup (eg. dom/webgpu/gpu.rs, bluetooth.rs).
- a new message is added to request a report from the memory reporter, and the memory reporter
  creates a json representation of the set of memory reports.
- the post-processing of memory reports is done in Javascript in the about-memory.html page,
  providing the same results as the current Rust code that outputs to stdout. We can decide
  later if we want to remove the current output.

f4d3af296c Move *_traits and other shared types to shared
This is the start of the organization of types that are in their own
crates in order to break dependency cycles between other crates. The
idea here is that putting these packages into their own directory is the
first step toward cleaning them up. They have grown organically and it
is difficult to explain to new folks where to put new shared types. Many
of these crates contain more than traits or don't contain traits at all.

Notably, `script_traits` isn't touched because it is vendored from
Gecko. Eventually this will move to `third_party`.
