Do not abbreviate items in element segments (#6737)

The full syntax for an expression in an element syntax looks like
`(item (ref.null none))`, but we have been printing the abbreviated
version, which omits the `(item ...)`. This abbreviation is only valid
when the item has only a single instruction, so it is not always correct
to use it. Rather than determining whether or not to use the
abbreviation on a case-by-case basis, always print the full syntax.
