Forwards compatible test changes for framework authorization [RUN AS-IF-FOSS]

See merge request gitlab-org/gitlab!48080

This uses the caching_array_resolver to eliminate the N+1 for
Epic.issues.

The filtering by accessibility is removed since we have authorization to
do that for us, which is tested in the request specs.

This updates some module doc comments, changes some variable names, uses
`global_id_of` in a few more places, and adds a new use of `before_all`.

Prefer to use the pagination shared examples

This mostly adds connection methods in preparation for the
graphql helper changes.

None of the changes in this commit should cause any observable
effects on application behaviour.

This includes

- removal of pagination tests from resolver specs (resolvers do not -
  currently - know enough of their arguments to make this work). At the
  moment we need to run all our pagination specs at the request
  integration level.

  This is the same for N+1 specs must always be run in request specs,
  since otherwise they are unreliable.
