Returns a fresh {@link MapMakerInternalMap} with {@link MapMaker.Dummy} values but otherwise as
specified by the given {@code builder}. The returned {@link MapMakerInternalMap} will be
optimized to saved memory. Since {@link MapMaker.Dummy} is a singleton, we don't need to store
any values at all. Because of this optimization, {@code build.getValueStrength()} must be
{@link Strength#STRONG}.

<p>This method is intended to only be used by the internal implementation of {@link Interners},
since a map of dummy values is the exact use case there.
