This type is a lot of complexity related to a very specific thing such as the
hover and active quirk.
Instead of that, move `nesting_level` to `MatchingContext`, and simplify all
this computing whether the quirk applies upfront, for each complex selector we
test.
This is less error-prone, and also allows simplifying more stuff in a bit.
Remove cssText from CSSStyleValue
Removed from associated .rs and .webidl

This introduces DeclarationSource, to see if a declaration has been parsed or
set from CSSOM in a declaration block.
The Servo_DeclarationBlock_SetFoo and similar callers are changed to
DeclarationSource::CssOm because their semantics are more CSSOM-y, but it
shouldn't matter since they should all be checked before hand with
Servo_DeclarationBlock_PropertyIsSet.
Serializing childrenonly
Rebased from #17896.

We don't store video-specific metadata anymore, and we don't ignore audio-specific
metadata anymore. We now just acknowledge that we received some metadata.

Associate WebGL textures with texture units
<!-- Please describe your changes on the following line: -->
Currently `bound_texture_2d` and `bound_texture_cube_map` fields are used to restore texture states and to get the current bindings in GetParams(...). But as soon as active texture is changed all the values can become dirty, leading to broken textures in some demos or invalid getParam(...) call results.
This PR implements the texture binding association with the texture units.

This Root<T> relies on the concept of a stable trace object, which doesn't
move for the whole lifetime of the T value. For safety reasons, T must be 'static.
The only implementor of StableTraceObject for now is Dom<T>.
In a later PR, DomRoot<T> will become a type alias of Root<Dom<T>>,
where Root<T> will be able to handle all the things that need to be
rooted that have a stable traceable address that doesn't move for the
whole lifetime of the root. Stay tuned.
I don't want to do such a gratuitous rename, but with all the other types
now having "Dom" as part of their name, and especially with "DomOnceCell",
I feel like the other cell type that we already have should also follow
the convention. That argument loses weight though when we realise there
is still DOMString and other things.
Removed integrity check and test for no-cors requests
Removed Step 30.2 which raised a JS TypeError if the integrity metadata was not empty. I manually ran `new Request("", {"mode" : "no-cors", "integrity" : "not an empty string"});` in servo to validate that the exception no longer arose.
