refactor: restructure packages to improve extensibility

[fgreinacher]

This change splits the System.IO.Abstractions package into TestableIO.System.IO.Abstractions and TestableIO.System.IO.Abstractions.Wrappers. The former contains just the interfaces and the latter the default wrapper implementations. The package System.IO.Abstractions still exists as meta package to reduce impact on existing users. The same applies to TestableIO.System.IO.Abstractions.TestingHelpers.

BREAKING CHANGE: This refactoring moves all types to the TestableIO.System.IO.Abstractions library. Users might need to recompile their libraries.

@fgreinacher : I finished my review :-)

Thanks for your comments @vbreuss, ready for round 2️⃣

@fgreinacher : Looks good!

What is the Benchmarks project?
Should it also have the "TestableIO" prefix?

It seems I can't resolve conversations or did I just not find the corresponding button?

It contains some performance benchmarks. I will also add the prefix there!

I guess that's because you're not member of the organization. If you're interested helping out here, just say so and I'll add you as collaborator.
