fix(reporters): properly determine flaky status for serial mode (#30529)
There are plenty of edge cases in this area:
- interrupted test run;
- did not run because of serial mode failure;
- failed before `test.skip()` call (e.g. in `beforeEach`) in one of the
retries;
- and more...

Related issues: #28322, #28321, #27455, #17652.
Prior changes: #27762, #26385, #28360, probably more.

There is still some duplication between `outcome()` and similar logic in
`base.ts`, which might be deduped in a follow-up.

Fixes #28322.
