Remove dependency_list usage counter

What does this MR do and why?

Remove dependency_list usage counter

For #219334 (closed)

This counter counting usage by project, resulting in an ever growing set in Redis as the feature gains adoption.

This data wasn't useful, while still consuming a relatively high amount of memory, so we removed it.

A better approach would be using Redis HLL counters for this.

Move the UsageCounter::PodLogs spec to FOSS

This feature was moved to Core in !26383 (merged) but we forgot this spec.
