encoding/asn1: sort order of 'SET of' components during Marshal

Per X690 Section 11.6 sort the order of SET of components when generating
DER. This CL makes no changes to Unmarshal, meaning unordered components
will still be accepted, and won't be re-ordered during parsing.

In order to sort the components a new encoder, setEncoder, which is similar
to multiEncoder is added. The functional difference is that setEncoder
encodes each component to a [][]byte, sorts the slice using a sort.Sort
interface, and then writes it out to the destination slice. The ordering
matches the output of OpenSSL.

Fixes #24254
