Add `counter list` and `counter info <handle>` commands, and list each
counter under its process in `profile info`, to inspect any counter
track from the terminal. Counters get stable `c-N` handles, like threads
and functions.
Per-counter stats come from the counter's own tooltip schema, reusing
the timeline tooltips' labels and formatters so the CLI and UI agree.
Stats respect the current zoom.
Closes firefox-devtools#6040

- Group counters under their process by counter.pid, as the timeline does.
- Add a getCommittedRangeCounterSampleSum selector and use it for the total.
- Drop the unused labelKey from counter stats; the CLI has no localization.
- Cover counter nesting with profile-query unit tests instead of an old fixture.

Both `counter list` and the counters nested in `profile info` follow the
timeline's track order (sortWeight, then name) instead of profile order.

- Drop the fixture-based counter integration tests.
- Cover the querier logic in profile-query unit tests with in-memory builders.
- Cover the text formatters in a fixture-free CLI unit test.
