Use dotnet format from SDK

- Use `dotnet format` from the .NET SDK instead of the `dotnet-format` tool which is deprecated and does not understand modern C# features like primary constructors.
- Fix warnings from `dotnet format`.
- Explicitly set the line endings to use for files.
- Downgrade `csharp_style_namespace_declarations` to a suggestion to avoid forcing adoption on existing files now and creating additional code churn.
