Use non-version-specific RID folders in NuGet package

[elinor-fung]

The Microsoft.Graphics.Win2D package includes native assets in win10-<arch> directories:

Win2D/build/nuget/Microsoft.Graphics.Win2D.nuspec

Lines 52 to 54 in e63db04

	<file target="runtimes\win10-arm64\native\Microsoft.Graphics.Canvas.dll" src="bin\UAPARM64\release\winrt.dll.UAP\Microsoft.Graphics.Canvas.dll" />
	<file target="runtimes\win10-x64\native\Microsoft.Graphics.Canvas.dll" src="bin\UAPx64\release\winrt.dll.UAP\Microsoft.Graphics.Canvas.dll" />
	<file target="runtimes\win10-x86\native\Microsoft.Graphics.Canvas.dll" src="bin\UAPx86\release\winrt.dll.UAP\Microsoft.Graphics.Canvas.dll" />

Starting with .NET 8, the .NET Runtime will not respect these directories and will only look in non-version-specific directories (win-<arch>). As a result, the assets under win10-<arch> will not be found.

The recommendation is to switch the package to using win-<arch> directories.

The .NET 8 SDK is also using a smaller simplified RID graph by default. When building for a specific RID, a non-version-specific win-<arch> should be used.

Just to provide an update for this here as well — we merged the fix for this already in the internal repo (Win2D on GitHub is just an upstream mirror of that one), and it will be included in the next feature release (1.1.1), to be released soon 🙂

A fix for this is now available, in version 1.1.1 of Microsoft.Graphics.Win2D 🙂
