GlassQualityStore class abstract

A pluggable backend for persisting GlassAdaptiveScope's settled GlassQuality across app cold starts.

Implement this to back GlassQualityPersistence with any storage layer (Hive, a database, a platform channel, ...). Most apps don't need a custom implementation — GlassQualityPersistence.auto ships a shared_preferences -backed one out of the box.
