Includes a memory leak in the checkqueue unit test (but not in the actual code). WE really need to switch our checkqueue to use std::unique_pointer rather than bare pointers. But this would be invasive enough that I want to do it in a followup PR. Also pretty-much disable the validation_flush_cache unit test. This is a stupid and irritating test which tries to unit-test exact memory usage of std containers. It already has at least one "remove wrong assumptions" update upstream and after many tries I was unable to change all the magic numbers in a way that'd consistently pass CI for Elements. Also adds a couple ubsan suppressions about perfectly-legitimate conversions of integer types.
