feat(core) Persist request_permission data across turns (#14009)

## Summary
request_permissions flows should support persisting results for the
session.

Open Question: Still deciding if we need within-turn approvals - this
adds complexity but I could see it being useful

## Testing
- [x] Updated unit tests
