feat: props memoization is more powerful

This commit solves the memoization , properly memoizing properties that don't have any generic parameters. This is a rough heuristic to prevent non-static lifetimes from creeping into props and breaking our minual lifetime management.

Props that have a generic parameter are opted-out of the `partialeq` requirement and props *without* lifetimes must implement partialeq. We're going to leave manual disabling of memoization for future work.
