Allow "unsafe" creation of a Queue

[kyri-petrou]

In zio-http, there are a few places where we need to create a queue "unsafely". Currently, this is done but unsafely running the effect, but this is both inefficient and also dangerous as we might end up blocking in cases that the effect might also perform some asynchronous tasks.

With this PR, we expose an option (currently available only to the zio namespace) to create a queue without running an effect

EDIT: Decided to make the object public. I really don't see a reason why we don't want to give users the option to do this

Any place it could be used internally?

There seem to be a few places it can potentially be used, but in almost all of those places it's composed with other effects so not sure if there's any benefit to do that
