Parity scope: Rust and Kotlin snapshot hydration is by schema id, not aliasing

Browse source 
F7 retires schema aliasing (one type presented as another for the same
schema). The Rust and Kotlin rows called their snapshot hydration "same-schema
alias" hydration. Both decode a raw record by its schema id into the one type
the receiving runtime registered for that schema; neither has a handle
aliasing API. The rows now say that.
