rustdoc: dedup search form HTML

[notriddle]

This change constructs the search form HTML using JavaScript, instead of plain HTML. It uses a custom element because

• the parser's insert algorithm runs the connected callback synchronously, so we won't get layout jank
• it requires very little HTML, so it's a real win in size

This shrinks the standard library by about 60MiB, by my test.

There should be no visible changes. Just use less disk space.
