Explore Generic Math for operations on IDataView & DataFrame

[lqdev]

A feature (Generic Math) was introduced in .NET 6 Preview 7.

https://devblogs.microsoft.com/dotnet/preview-features-in-net-6-generic-math/

It essentially allows you to "...use operators on generic types. ".

This might be useful / make it easier to apply operations using VBuffer and DataFrameColumn types.

Yes, though we'd only be able to use it on .net6.0 and even there only as a preview. It might be interesting to see what changes this might allow us to do, but since it's preview we'd have to be careful about taking a dependency on it in our production library.

This feels resolved by #7179.
