[dotnet] Add net10.0 msbuild tool DLLs to SignList.xml (#25006)

The dotnet/dotnet dependency update (#24989) introduced new DLLs in the
tools/msbuild/net10.0/ directory of the SDK NuGet packages. These DLLs
were not listed in SignList.xml, causing the 'Sign Package Contents'
task to fail in the xamarin-macios-ci pipeline (build 13640795).

Add 18 DLLs as Skip entries since they come pre-signed from the
dotnet/dotnet unified build.
