[Debugger Visualizers] Unify *-gnu and *-msvc enum output

[Walnut356]

Followup patch to #145218

Ports the msvc enum synthetic/summary logic to the gnu handlers so they have identical output. Also removes the "look-through-pointers" logic that caused #147450

I know we don't run the test suite in CI anymore, but it's still useful locally so I updated the relevant tests.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
