Builds a cache which does not automatically load values when keys are requested.

<p>Consider {@link #build(CacheLoader)} instead, if it is feasible to implement a {@code
CacheLoader}.

<p>This method does not alter the state of this {@code CacheBuilder} instance, so it can be
invoked again to create multiple independent caches.
