Clean up and document the `send_display_list` interface
This moves more members to the CompositorDisplayListInfo struct, which now holds all miscellaneous, non-WebRender data when sending display lists. It also documents what each things sent with a display list does.

Implement `bootstrap-gstreamer` for all platforms
This change makes it so that the Platform classes can now handle installing GStreamer dependencies and properly setting up the environment including when cross-compiling. For Windows and Linux, prepackaged GStreamer is now installed into `target/dependencies/gstreamer` when not installed system-wide. In addition this change:
1. The Environment path append helper is moved to `util.py` and a new `prepend` version is added.
2. `set_run_env` and `build_dev` functions are combined and include more code from callers so environment setup is more often in the same place. Now code that used to call `set_run_env` calls `build_dev` and then `os.environ.update(...)`. We can further refine this with the `is_build` argument later.
4. Python typing information is added in many places.

Upload nightly builds for layout2020 variant
<!-- Please describe your changes on the following line: -->
We'd like to start offering servo nightly builds with layout 2020 engine so that users can test the new layout without building servo. These new builds will be offered in addition to the current 2013 builds until we switch over to 2020 as the default.

This change makes it so that the Platform classes can now handle
installing GStreamer dependencies and properly setting up the
environment including when cross-compiling. For Windows and Linux
is now installed into `target/dependencies/gstreamer` when not installed
system-wide. In addition:
1. Creating and moving existing environment path append helpers to
`util.py`.
2. Combining the `set_run_env` and `build_dev` functions and moving
some outside code into them so that it can be shared. Now code that
used to call `set_run_env` calls `build_dev` and then
`os.environ.update(...)`.
3. Adding Python typing information in many places.

Remove outdated note on README (fix#29786)
This patch just removes a note about building only servo vs libsimpleservo binaries, as that's no longer working.
break-before/after: page|column seem harder because you need to deal
with nested breaks, I think, but this should be straight-forward.

We probably want to do this when they do something different, but for
now behavior should be the same and it causes some subtests to fail
because `getComputedStyle(..).fontFamily` for system fonts seems to
return -apple-system, but `.style.fontFamily = "-apple-system"` returns
`system-ui`.
MANUAL PUSH: Orange fix on a CLOSED TREE
This was being used when we had special code for gecko profiler in the servo
codebase but we just removed the last one. This is safe to remove now. The
"enabled" feature in the gecko-profiler crate is being controlled by
gkrust-shared directly now.

While the use of toml allows the flags to be separated, the split is
done via some shell shenanigans anyways, and servo's build.rs can
handle the same just fine.

Add initial support for the color-scheme CSS property, allowing pages to
choose between light and dark system colors per-element, and such.
Things that are left to do so that this can be enabled by default:
* Dark system colors on Windows / Android / Standins.
* Dark Canvas/CanvasText/Link visited colors (which right now are set
via PreferenceSheet).
* Dark form controls in nsNativeBasicTheme.
* Processing the color-scheme meta tag to fill-in
Document::mColorSchemeBits.
But this seems like enough progress to be landable on its own.

Alias -apple-system to it, and put it behind a pref for now. This is
pretty boring (read: uncontroversial hopefully) code. The follow-up work
is modifying StaticPresData to look up the fonts using system APIs,
probably. Maybe a bit more work if on macOS they can't be named.

Instead, fix up the various content data structures when the stylesheet
is mutated. This makes reading a stylesheet not disable style sharing.

It's very hot when matching some kind of selectors like the ones in bug
1717267, and the two function calls show up in the profiles.
