[UWP] Key events
This is the initial work required for proper keyboard events.
The text controller implementation is very basic, just enough to show the virtual keyboard when it's needed, and have basic key events.

This is based on compiling with `RUSTFLAGS="-W unused_crate_dependencies"` (CC https://github.com/rust-lang/rust/pull/72342) in a recent Nightly (more so than used in the tree as of this writing, CC https://github.com/servo/servo/issues/26661 for work-arounds).
Only one crate is actually removed from the dependency graph, others are still dependended from other places.
This is preparation for sharing this code with layout_2020 and
implementing selective off-the-main-thread animations.
We still look for nodes not in the flow tree in the layout thread.
This change corrects synchronization issues with animations, by
reworking the animation processing model to do a quick restyle and
incremental layout when ticking animations.
While this change adds overhead to animation ticks, the idea is that
this will be the fallback when synchronous behavior is required to
fulfill specification requirements. In the optimistic case, many
animations could be updated and applied off-the-main-thread and then
resynchronized when style information is queried by script.
Fixes#13865.
Changed the Requests/Response from tuples to named struct variants and also sorted in alphabetical order.
Replaced the ID generator functions from `globalscope` with a single function,
which returns a `RefMut` and can call the appropriate method to generate resource IDs.
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.
Hide window
Stop animations when the window is hidden.
Tested with both Immersive Mode, and regular window being minimized.

move `ConstellationCanvasMsg` to canvas_traits and start canvas paint thread
to components/servo. This, however, does not remove dependency for conditional
compilation options.
