Champion: numeric IntPtr

[jcouv]

numeric IntPtr

Summary

System.IntPtr and System.UIntPtr become numeric types, aliased by nint and nuint, and gain the built-in status of nint and nuint.

Motivation

As part of numerics work for .NET 7, System.IntPtr and System.UIntPtr are becoming proper numeric types.
So the distinction between native integer types and their underlying types becomes unnecessary.

@jcouv looks like https://github.com/dotnet/csharplang/blob/main/proposals/numeric-intptr.md is broken.

Yes, the spec is still only a draft PR for now. The link will work by next week.
