Renamed constellation::Frame to constellation::BrowsingContext
<!-- Please describe your changes on the following line: -->
Now that script has `WindowProxy` rather than `BrowsingContext` objects, we can rename `Frame` in the constellation to `BrowsingContext`. In particular, this means that `FrameId`s are now `BrowsingContextid`s, which better captures their purpose (and they are used in a lot of places, not just the constellation).

Scroll roots are no longer nested containers holding items, so instead
we need to track the offsets of each, carefully handling fixed position
items and stacking contexts that create new reference frames.
Additionally, we remove the complexity of the pre-computed page scroll
offset, instead opting to send script scrolls to the layout task in
order to more quickly have a ScrollState there that matches the
script's idea of the scroll world.
Fixes #16405.

This avoids the need for multiple layout RPC operations immediately
following return of control to script. This means that layout and
script can continue to operate in parallel at this point, rather
than one potentially waiting on the shared mutex to be unlocked.

This ensures that we can pass a node address as part of the asynchronous
transition end notification, making it safe to fire the corresponding
DOM event on the node from the script thread. Without explicitly rooting
this node when the transition starts, we risk the node being GCed before
the transition is complete.

Fix unsafe AtomicRefCell<T> transmutes in Layout component
<!-- Please describe your changes on the following line: -->
Fixes unsafe transmute between `AtomicRefCell<PersistentLayoutData>` and `AtomicRefCell<PartialPersistentLayoutData>` which have different memory alignment in 32 bit archs leading to SEGV crashes. See https://github.com/servo/servo/issues/16817 and https://github.com/servo/servo/pull/16816
mem::align_of values in 32 bit archs (e.g. Android):
```
PersistentLayoutData 8
PersistentLayoutData 4
AtomicRefCell<PersistentLayoutData> 8
AtomicRefCell<PartialPersistentLayoutData> 4
```
mem::align_of values in 64 bit archs
```
PersistentLayoutData 8
PersistentLayoutData 8
AtomicRefCell<PersistentLayoutData> 8
AtomicRefCell<PartialPersistentLayoutData> 8
```

Don't update iframe pipeline until load completes
To preserve the previous functionality of delaying load events when a
new navigation is triggered, pending pipeline id represents the
current pending load. The load event is only fired if the load message's
pipeline id matches the pending pipeline id.
Track frame size on Frame instead of Pipeline
Disabled matchMedia test
Track creator pipeline id

Just use WebRender's ClipId directly. This will allow us to create and
use ReferenceFrames in the future, if we need to do that. It will also
make it easier to have Servo responsible for creating the root
scrolling area, which will allow removing some old hacks in the future.

Since for nested inline elements non-inheritable properties are
properly stored in the inline context of an inline fragment, so get
rid of them on the style.

Now that cascade() gets a Device, we can use the default computed values from
there to avoid propagating that state all over the place.

In support of this goal, the layout thread collects information about
CSS images that are missing image data and hands it off to the script
thread after layout completes. The script thread stores a list of
nodes that will need to be reflowed after the associated network
request is complete. The script thread ensures that the nodes are
not GCed while a request is ongoing, which the layout thread is
incapable of guaranteeing.
The image cache's API has also been redesigned in support of this
work. No network requests are made by the new image cache, since it
does not possess the document-specific information necessary to
initiate them. Instead, there is now a single, synchronous
query operation that optionally reserves a slot when a cache
entry for a URL cannot be found. This reserved slot is then
the responsibility of the queryer to populate with the contents
of the network response for the URL once it is complete. Any
subsequent queries for the same URL will be informed that the
response is pending until that occurs.
The changes to layout also remove the synchronous image loading
code path, which means that reftests now test the same code
that non-test binaries execute. The decision to take a screenshot
now considers whether there are any outstanding image
requests for layout in order to avoid intermittent failures in
reftests that use CSS images.

Sometimes clippy gets outdated by months, and its current support setup
means that each Servo component need to opt into it by depending on
the plugins crate manually, and not all components do that.

This is necessary to start synthesizing the styles in match_element and avoid
round-tripping them through the caller.
