Add stable sort for Array module
Seq.sort and List.sort are based on Microsoft.FSharp.Primitives.Basics.Array.stableSortInPlace, so there are stable sort. But Array.sort is unstable. This is confusing.
Please be public the function Array.stableSortInPlace, etc.
Declined: This is really a .NET thing

This really depends on .NET providing an efficient stable sort for arrays. It doesn't. Searching for "stable sort array c#" gives useful guides about what to do.
