Pack symbols in SharedFx for libraries we redist from runtime

Includes .pdb's in the SharedFx for libraries we re-dist from runtime.

Description

We've never included these in the past, but that was fine in the past because every aspnetcore RID consumed the win-x64 runtime transport pack, which corresponded to the packages that went on nuget. Now that we build in verticals in the VMR, only the win-x64 aspnetcore leg builds against libraries that match the symbols on nuget.org, so symbols aren't available for runtime libraries in our SharedFx on non-win-x64 platforms. Therefore we should explicitly include the .pdb's in the SharedFx to make them available.

Fixes #62165

Pull Request Overview

This PR backports support for including PDB symbols in the SharedFx for libraries redistributed from the runtime, ensuring symbols are available on non-win-x64 platforms.

• Injects a new _AddExtensionsSymbolsToSymbolPack target into the build dependency chain.
• Adds a PackageReference for Microsoft.Internal.Runtime.AspNetCore.Transport with GeneratePathProperty.
• Defines logic to filter and include symbol files (.pdb) for external ASP.NET Core libraries.

File	Description
src/Framework/App.Runtime/src/Microsoft.AspNetCore.App.Runtime.sfxproj	Added transport package reference and _AddExtensionsSymbolsToSymbolPack target to pack PDBs.
src/Framework/App.Runtime/src/Microsoft.AspNetCore.App.Runtime.Composite.sfxproj	Mirrored the symbol-packaging target and enabled DisablePackageReferenceRestrictions.

• The Condition expression uses $(FileNameList.Contains(...)), which isn’t valid MSBuild syntax. Replace it with an MSBuild property function, e.g.:

Condition=" '$(FileNameList)' != '' and $([System.String]::Copy('$(FileNameList)').Contains('%(Filename);')) "

          Condition="'$(FileNameList)' != '' and $(FileNameList.Contains('%(Filename);'))" />

• The Condition filter for _SymbolFilesToPackage won’t work as written. Use an MSBuild string function, for example:

Condition=" '$(FileNameList)' != '' and $([System.String]::Copy('$(FileNameList)').Contains('%(Filename);')) "

          Condition="'$(FileNameList)' != '' and $(FileNameList.Contains('%(Filename);'))" />
