Support single-value <select> elements (#35684)
https://github.com/user-attachments/assets/9aba75ff-4190-4a85-89ed-d3f3aa53d3b0 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. <details><summary>HTML for demo video</summary> ```html <html> <body> <select id="c" name="choice"> <option value="first">First Value</option> <option value="second">Second Value</option> <option value="third">Third Value</option> </select> </body> </html> ``` </details> --- <!-- Thank you for contributing to Servo!
