Avoid String.format in state namespace key construction

Build test failures look like unrelated spark test issues creating
directories in jenkins? 🤷♂

> I've noticed that for jobs that access state frequently, a percent or two of
> overall CPU time is actually spent calculating the state namespace name.
> StateNamespaces.java uses a String.format for the window namespaces, but
> could simply use a string concatenation to do the same thing with much less
> overhead.
