Skip EnsureCodeFixesProjectBuilt target when NoBuild=true

dotnet pack --no-build sets NoBuild=true, which prohibits invoking the
Build target. The custom EnsureCodeFixesProjectBuilt target was doing
exactly that, triggering NETSDK1085. Adding the condition makes the
target a no-op when the caller has already asserted everything is built.
