Incremental generator implementation

[laicasaane]

Since the support for Microsoft.CodeAnalysis.CSharp 4.1.0 has been added to Unity 2022.2+, could you start working on incremental generator? Thanks.

I've double-checked it and found out that Microsoft.CodeAnalysis.CSharp 4.1.0 have already been supported for Unity 2021.3.26f1.

I'd like to second wanting LinqGen to be an incremental source generator. I know it will be a large undertaking, but currently with it being a first gen non-incremental source generator, it causes very large projects to lag Visual Studio in most aspects and is very unworkable at that point. I've been trying to benchmark LinqGen against a lot of other LINQ implementations and as said project is very, very large due to the number of benchmarks, just adding a LinqGen to the project reduces functionality of Visual Studio by a lot.
