GraphQL: Add lazy loader for blocking epics count

Eugenia Grieff requested to merge 355739-lazy-loader-epics-blocking-count into master

What does this MR do and why?

Related to #355739 (closed)

When querying an epic's blocking count with GraphQL we are getting N+1 queries:

query epicBlocksData {
  group(fullPath: EPIC_GROUP_PATH) {
    epic(iid: EPIC_IID) {
      blockingCount
    }
  }
}

This MR extends Issuables::LazyBlockAggregate to take an extra query_type argument, which makes it be able to lazy load blocking data as well as the existing blocked data.

See !87830 (comment 964949630) for more context.
