feat(internal): Added RecycledQueue class

[st-pasha]

Description

This PR introduces RecycledQueue class, which is similar to a regular FIFO Queue except that it supports recycling of objects instead of having to create/delete them all the time.

This class will be used to build more efficient component lifecycle queues.

Lgtm! Not too fond of the utils directory becoming a place with a wide mix of things in it though, maybe the two existing files in there could be put in some math directory, and this one be placed somewhere else or having the utils directory renamed?

To me, "utils" sounds a bit like "miscellaneous" (but easier to spell :).
So, where would you suggest the RecycledQueue class be located?

Indeed, that's what I'd like to avoid, to not have a place where non-related files live.
Maybe a new directory in components called lifecycle? And then maybe the LifecycleManager could be moved there too?

I created the directory components/core then, seems like it would have a larger scope than mere lifecycle.

Very nice!
