feat: Async init

[robha141]

Added new AsyncContainer, with async registration and resolution of dependencies.

Well, I apologize for request changes, but I just wanna you double check the solution as well. There are many similarities in all those typealiases for "factories" but some of the types are not very understandable - although it's async copy paste of existing.
I know we're adding new "feature" without breaking changes, at the same time we created async DI for exploring swift6 complete concurrency check really fast way, therefore I'm for double check.

Very handy! I have just a few documentation and tests comments.

I just looked at it briefly and left one thought. I'll do more throught review once I have more time. 😊

@robha141 Kudos. Impressive work. Please consider the change in the folder structure - maybe we can put Sync and Async variants of code into separate subfolders. What do you think?

And maybe silly question. If I have the same dependency that I need in both sync and async contexts, should I have two registrations? Can we somehow unify the interface as @cernym46 suggested?

I made the changes in the structure. Those changes are rather cosmetic but they allow to divide of synchronous, asynchronous, and common parts of the code.

Great job! I didn't find anything that would have effect on the usage. Just few naming/documentation notes and one nitpicking edgecase.
