[msbuild] Bump to Microsoft.Build 16.10.0.

[rolfbjarne]

This seems to be the version in Mono: mono/mono#21073

In particular we need the IBuildEngine9 interface, because the ILStrip task needs it:

https://github.com/dotnet/runtime/blob/3aa1ec5bb1f50f0a1bed9cfcac8734f742bcf24b/src/tasks/MonoTargetsTasks/ILStrip/ILStrip.cs#L78

The IBuildEngine9 interface was introduced in MSBuild 16.10 (around March 2021):
