Refactor common infrastructure for creating memory reports. (#36579)

Browse source 
This removes a bunch of duplicated code needed to support
ConditionalMallocSizeOf correctly, and fixes multiple places where that
code was subtly wrong (the seen pointers hashset was never cleared).

Testing: Measuring https://www.nist.gov/image-gallery lots of times.
