Use System.CommandLine library for convinient CLI command parsing

[zrckr]

Ok, this is a big one...

For more convenient development of current and future commands for the CLI, I suggest using the System.CommandLine library. This is used for the dotnet utility and provides an API for creating CLIs. It is currently in the rc stage, but its API is quite stable.

Advantages:

• Supports many native C# types that automatically convert data (for example, enums, file and directory infos).
• No reflection-based API.
• Quite small (~153 KB) and no external dependencies.

Disadvantages:

• The library currently is in preview stage (mentioned above).
• Microsoft's documentation is still sparse, describing only the basic principles of working with the library.

For now this PR is adraft because it contains many changes. In terms of functionality, (almost) everything has remained the same (except for the help command, which is generated by the library).

A self-contained executable is compiling without errors. The only thing is that the library warns about being tailored for .NET 8.0, but (so far) it compiles fine under .NET 6.0.

Out of curiosity, how much would it hurt us to retarget Repacker CLI to .NET 8.0?

I ran an experiment with two SDKs (changed the target framework on FEZRepacker.Interface and FEZRepacker.Tests).
Command used: dotnet publish -c Release -r win-x86 --self-contained

SDK 8.0.414, TargetFramework net8.0:
