Store raw string for prop decl in @supports
This fixes the serialization issue of `@supports` rule that whitespaces are not preserved like in other browsers.
It makes the work a bit redundant (the property name and colon is parsed twice), but I suppose this isn't a big deal.

This allows us to have ensure_data() and clear_data() functions on the TElement
trait, instead of hacking around it adding methods in random traits.
This also allows us to do some further cleanup, which I'd rather do in a
followup.
Have CharacterData call children_changed on its parent when data is set.
**Can't run WPT on my computer, so pushing here to run tests 😢**
Have CharacterData.SetData call children_changed on its parent when
data is set (if it is a Text node) so that HTMLStyleElement parents can
re-parse. Add variant ChildrenMutation::Text for it to use as the
mutation.
This fixes an issue where an empty <style> element's data is set but the
style is not updated. An HTMLStyleElement parent re-parses in its
children_changed implementation.

This reverts commit ebfc8f5858, reversing

Animation code can reenter and create a new TLS context from the traversal
SequentialTask, so this won't work as written.
We parse when assigning using the namespaces of the stylesheet. It isn't
clear if the spec says to do that (Firefox doesn't support the setter at
all, Chrome does, Safari doesn't); the spec issue is here:
https://github.com/w3c/csswg-drafts/issues/1511
Also fix ToCss implementation of AttrSelectorOperator to not pad with
spaces, to conform with CSSOM. This means we have to update some unit
tests that expect operators with spaces around them in attribute
selectors to roundtrip.
See the "attribute selector" section of "Serializing Selectors" here:
https://drafts.csswg.org/cssom/#serializing-selectors
CSSStyleRule.selectorText is specified here:

Implement paint worklet properties
<!-- Please describe your changes on the following line: -->
This is the final PR to get basic paint worklet support. It adds support for paint worklet properties (https://drafts.css-houdini.org/css-paint-api/#paint-definition-input-properties). When a paint worklet is registered, it specifies a list of CSS properties, and is provided with their computed values when it is invoked.
This is a dependent PR:
* "Implemented paint worklets invoking worklet scripts" is #17239.
* "Implemented paint worklets rendering contexts" is #17326.
There should be tests added for this, hopefully the existing wpt houdini tests.
