Rework derived state (#7290)

* Remove derived state from state classes

* Create provider for derived state

Derived state is automatically stored to memory storage, but can be derived from any observable.

* Fixup state provider method definitions

* Test `DefaultDerivedState`

* remove implementation notes

* Write docs for derived state

* fixup derived state provider types

* Implement buffered delayUntil operator

* Move state types to a common module

* Move mock ports to centra location

* Alias DerivedStateDependency type

* Add dependencies to browser

* Prefer internal rxjs operators for ref counting

* WIP

* Ensure complete on subjects

* Foreground/background messaging for browser

Defers work for browser to the background

* Test foreground port behaviors

* Inject foreground and background derived state services

* remove unnecessary class field

* Adhere to required options

* Add dderived state to CLI

* Prefer type definition in type parameters to options

* Prefer instance method

* Implements factory methods for common uses

* Remove nothing test

* Remove share subject reference

Share manages connector subjects internally and will reuse them until
refcount is 0 and the cleanup time has passed. Saving our own reference
just risks memory leaks without real testability benefits.

* Fix interaction state
