Jonas Jenwald 9881dbf927 Attempt to also cache images at the "page"-level (issue 16263)
Currently we have two separate image-caches on the worker-thread:
 - A local one, which is unique to each `PartialEvaluator.getOperatorList` invocation. This one caches both names *and* references, since image-resources may be accessed in either way.
 - A global one, which applies to the entire PDF documents and all its pages. This one only caches references, since nothing else would work.

This patch introduces a third image-cache, which essentially sits "between" the two existing ones. The new `RegionalImageCache`[1] will be usable throughout a `PartialEvaluator` instance, and consequently it *only* caches references, which thus allows us to keep track of repeated image-resources found in e.g. different /Form and /SMask objects.
