We need to figure out exactly how to queries should work. This is especially important when we also consider suspend functions.

In Realm Java we right now have a `RealmQuery` class you can call method like `findAll()`, `findAllAsync()` or `findFirst()` on.

In Realm Kotlin we most likely will expose the string based Core API. Swift/JS both have an lazy-evaluated approach to this.

Questions/TODO:

• What does an Kotlin idiomatic API look like?
• How can it be supported both synchronously and from suspend functions?
• We need to define use cases, e.g. how does synchronous queries look like? Suspend queries?
• Would we except a subpar experience for synchronous queries if suspend query support is excellent?
• Write up design doc with proposal and pros/cons.
