script: use Element::create instead of DOM struct constructors (#39325)

Creating elements by directly calling their interface constructors leads
to some state not being intialized correctly (see #39285). It is also
not in line with the specifications as many of them refer to the
[`create an element`][1] algorithm when an element needs to be created,
which directly maps to `Element::create` in the script crate.

So, switch all such places where elements are created by script to use
`Element::create`.

Testing: Existing WPT tests.

Fixes: #39285
