feat: Immutable builder for interceptor and supervisor

[Roiocam]

Draft because I haven't verified everything and I am not sure if this is the optimal approach.

Example usage could be like this:

val rawBehavior: Behavior[Command] = Behaviors.empty
val interceptor : BehaviorInterceptor[Command,Command] = ???
val monitorProbe = TestProbe[Command]("probe")

val behavior: Behavior[Command] = Behaviors.interceptorBuilder(rawBehavior)
  .onFailure[Exc1](SupervisorStrategy.restart.withStashCapacity(100))
  .onFailure[Exc2](SupervisorStrategy.restart.withStashCapacity(100))
  .intercept[Command](() => interceptor)
  .onFailure[Exc3](SupervisorStrategy.restart.withStashCapacity(100))
  .monitor(monitorProbe.ref)
  .build()

After incrementing some additional methods, I have discovered that most of the methods can be flattened using this builder. It seems to be more like a BehaviorBuilder rather than an InterceptorBuilder.
