Use new and new_inherited in messagechannel
<!-- Please describe your changes on the following line: -->
Use common DOM constructor idioms in `MessageChannel`. Also, remove the falliable from the result, since that seems to match the spec better https://html.spec.whatwg.org/multipage/web-messaging.html#dom-messagechannel

Delay reftest screenshot while WR frame is rendering
This PR addresses the theory that #24726 occurs when WR is performing an async frame render and the reftest screenshot decides it's time to synchronously read the framebuffer. If there have not been any completed frames rendered yet, that would yield the page background colour.
The changes in this PR introduce an additional layer of synchronization - the compositor stores an AtomicBool value that indicates whether we know that a WR frame has started rendering, which is set to true when an IPC request from layout that submits a new display list is received. This bool is set to false when WR notifies us that a frame has been rendered. The screenshot code refuses to take a screenshot if the bool is true, causing us to delay taking a screenshot until there is no frame pending.
Add support for WebGL2 framebuffer attachments

Synchronize ANGLE linking path with VS project.
This avoids problems when upgrading or downgrading the ANGLE NuGet package from Visual Studio. The next time the Rust code needs to be linked, it's common to forget to update the path in build_commands.py, leading to surprising linker errors. By reading the current package version from the VS project configuration, we avoid this papercut.
Hide window
Stop animations when the window is hidden.
Tested with both Immersive Mode, and regular window being minimized.

Thread vslatestinstalled feature to the top
I've been building with this to get pure-VS 2019 to work. Ideally we don't need any extra flags, but for now at least worth getting into master so I don't have to cherry pick this all the time.

Take origin from current window instead of creating a new one in event of reflow
Everytime a new `LayoutContext` was created, it created a new origin which
caused endless stream of image loads to occur in case of reflow. The reason
for this was that the existing image, although cached successfully, was not
used because the entry in hashmap did not match because of different(new)
origin.
This is solved by storing the origin of a window in enum `ScriptReflow` and
used in creating new `LayoutContext` in case of reflow.

After WPT moves to "Manifest path trie RFC", we don't have the `paths`
field in manifest anymore.
But, we still have file hash in the `items` field; the simplest way to
diff between manifests is to compare the raw string value of the `items`
field. When we have different manifests, we must have different items
field in the manifest json.
