Share single gpu_id_hub among all threads in a process
<!-- Please describe your changes on the following line: -->
An id_hub for a content process is created when a new script thread is created. This is then cloned whenever a new globalscope object is created. The only exception being service workers because they exist in separate processes, for them a new hub is created.

Reject incompatible webgl texture pixel data
The tests that would make these changes most visibly correct unfortunately rely on texImage3D which isn't implemented yet, so they error out too soon. However, when I comment out that code, these changes avoid a bunch of panics in the webgl thread because of invalid data type combinations being accepted, and removing the incorrect non-filterable texture fallback behaviour for webgl 2 when more texture formats are supposed to be filterable.

Fix an issue with the rooting of animating nodes
Make sure nodes removed from map of rooted animating nodes are rooted on
the stack before triggering event handlers. We also make sure not to
call `from_untrusted_node_address` on nodes that aren't guaranteed to be
rooted.
Fixes#26498.

Handle cancelAnimationFrame() when called within a requestAnimationFr…

<!-- Please describe your changes on the following line: -->
In order to handle `cancelAnimationFrame()` in the callback, the `raf_callback_list` is moved to
`current_raf_callback_list`, and each callback is cloned in the iteration of `current_raf_callback_list` to avoid "borrowed twice".

This removes an extra layer of abstraction and allows Servo to share
more code with Gecko. In addition, we will need to handle raw
`AnimationValue` structs soon in order to fully implement "faster
reversing of interrupted transitions."
Make sure nodes removed from map of rooted animating nodes are rooted on
the stack before triggering event handlers. We also make sure not to
call `from_untrusted_node_address` on nodes that aren't guaranteed to be
rooted.
Fixes#26498.
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.
Add support for getComputedStyle() to layout_2020
These changes add support for `getComputedStyle()` to layout_2020.

This implementation is more-or-less on par with the one from layout_2013
and in some cases better. There are still some cases where we don't
return the correct "resolved value," but this is enough to test
animations and transitions.
layout_2020: Add support for transform-style
This requires creating a matching stacking context for every reference
frame and also properly placing those stacking contexts inside them.

Initiate redirect fetching iff the request has a location
Without this checking, we will run into a TIMEOUT request because
http_redirect_fetch will return immediately when location doesn't exist.

The image cache returns an `ImageCacheResult::ImageAvailable `the second
time you try getting the placeholder. This means that in some cases, the
loading of an image would fail, then the same image would get fetched
from the cache, the placeholder would be loaded from that but would be
seen as a normal image, firing a load event.
This made the tests in
`fetch/cross-origin-resource-policy/image-loads.html` fail depending on
their order.
Add referrerpolicy to list of relevant mutations
<!-- Please describe your changes on the following line: -->
`img.referrerPolicy` change now mutates the image.
Not all `referrerPolicy` attribute changes result in an image update event.
Only valid changes are reflected.
All referrerpolicy tests inside `relevant-mutations.html` WPT test now pass.

mutations. Not all referrerPolicy attribute changes result in an image
update event. Only valid changes are reflected.
Referrerpolicy tests now pass.
This change splits the list of animations and transitions, which are
almost always handled differently. It also renames
`ElementAnimationState` to `ElementAnimationSet` and establishes an
`AnimationState` for every transition and animation. This allows us to
stop continually reallocating lists every time a transition or animation
needs to be canceled.
Fixes#14419.
Have animations more closely match the HTML spec
These two commits do two major things:
**Have animations ticks trigger a restyle**: This corrects synchronization issues with animations,
where the values used in layout are out of sync with what is returned by `getComputedStyle`.
**Tick the animation timer in script according to spec**: This greatly reduces the flakiness of
animation and transitions tests.
Fixes#13865.

This doesn't change any expectation because we're not setting
response.redirected properly so all the tests fail later on when it's
asserted to be true.
Fixes#25257

This is a small step toward fixing #19242. The main idea is that the
clock for animations should advance as the event loop ticks. We
accomplish this by moving the clock from layout and naming it the
"animation timeline" which is the spec language. This should fix
flakiness with animations and transitions tests where a reflow could
move animations forward while script was running.
This change also starts to break out transition and animation events
into their own data structure, because it's quite likely that the next
step in fixing #19242 is to no longer send these events through a
channel.
