[SIL Cloner] Only substitute opened archetypes into conformances when needed.
[SIL Cloner] Only substitute opened archetypes into conformances when needed.

Substitution can be expensive; only do it when there might be something to
substitute. While here, use QueryTypeSubstitutionMapOrIdentity rather than
open-coding the same thing in a lambda.
