Import Common.props after the Arcade.SDK in props file (#59309)

The Common.props file now depends on the `DotNetBuild` property which isn't available before the Arcade SDK is imported.
Therefore move the import down after the Arcade SDK is imported.
I verified (for every single property defined in Common.props) that it isn't used anywhere in the Arcade.SDK or in aspnetcore before where it's now imported.
