This change adds a shadow-tree widget for `<input type=color>` elements.
It also involves some changes to the way layout interacts with the DOM,
because currently all `input` and `textarea` elements are rendered as
plain text and their descendants are ignored. This obviously doesn't
work for `<input type={color, date, range, etc}>`.

<details><summary>HTML used for the screenshot above</summary>
```html
<input type=color>
```

Testing: I doubt that this affects WPT tests, because the appearance and
behaviour of the widget is almost entirely unspecified.

This PR updates the validity state revalidation behavior for radio input
elements, ensuring consistent logic regardless of tree connectivity.
---
**What’s changed:**
- we now always update the validity state.
- Handled more edge cases for disconnected trees, shadow roots, and
cross-tree movement.
- Ensured that radio group updates still trigger when a parent is moved
into a different root.
- Updated test expectations in
`radio-disconnected-group-owner.html.ini`.
---
**Why this matters:**
The updated logic aligns better with the [HTML
specification](https://html.spec.whatwg.org/multipage/input.html#radio-button-group),
especially regarding radio group behavior in disconnected trees or
shadow DOM.
These changes improve validity propagation in scenarios like:
- Appending inputs into a disconnected form
- Shadow roots acting as radio group containers
- Cross-tree movement of radio buttons
---
**Tests:**
- Modified `radio-disconnected-group-owner.html.ini`
- Removed a test that now passes
- Added a failing test expectation caused by a spec bug: the fragment
parsing algorithm uses the connected tree for HTML set via `innerHTML`,
affecting radio group computation

Among other things this adds a new `EmbedderMsg::ShowSelectElementMenu`
to tell the embedder to display a select popup at the given location.
This is a draft because some small style adjustments need to be made:
* the select element should always have the width of the largest option
* the border should be part of the shadow tree
Apart from that, it's mostly ready for review.

Changed `RegExpFlag_Unicode` to `RegExpFlag_UnicodeSets` in all
instances.
Testing: Ran `./mach test-wpt
tests/wpt/tests/html/semantics/forms/constraints/form-validation-validity-patternMismatch.html`
and all tests passed successfully.
Fixes: #36075

The HTML specification states that an input element with the `readonly`
attribute must be barred from constraint validation. Our implementation
previously included an extra check (`does_readonly_apply()`) to verify
if `readonly` applies to the input type, which is unnecessary.
This caused three test failures in:
tests/wpt/meta/html/semantics/forms/constraints/form-validation-willValidate.html.ini
- Removed `does_readonly_apply()` as it is not required for validation.
- Removed `tests/wpt/meta/html/semantics/forms/constraints/form-validation-willValidate.html.ini` since the test now passes.

* Don't falsely register Shadow Roots as connected
Previously, a shadowroot would be registered as connected
during the shadow hosts bind_to_tree call, even if the host
was being bound to an element that was not itself
