* fix double-build of vsix packages (#6232)

* Update Microsoft.FSharp.vsmanproj

* Update mono props: support OSX and more .NET Framework versions

A potential solve for #6180 that uses msbuild built-ins to determine the target OS and pivots off of that to set the FrameworkPathOverride.  I included a `MonoRoot` property to allow for easy integration into the build process that fsharp/fsharp uses, which allows for a 'floating' mono root.

* add osx build jobs matching the linux jobs, and add a matrix entry to build the compiler for .net framework using mono

* don't try to build anything for .net framework on non-windows

this required additional build work that may conflict with upcoming work, so we'll just settle for building the existing components on macos at all in CI

* Update range.fs

* possible fix for signature issue

* fix de-duplication

Fixes #6068, where you could cause a `System.OverFlowException` by using a key and value that leads to calling `abs` on `Int32.MinValue`. This is invalid on .NET. The fix is to not call `abs`, since there's really no reason to make a hash code always positive.

* remove allocations from jaro

* improve perforamce

* fix build

* remove string concat allocations from FilterPredictions

* fix build

* move to struct tuple and remove the concat completely
