Refactor AfterCommitQueue.inside_transaction?

See merge request gitlab-org/gitlab-ce!29903

This is a small change to move AfterCommitQueue.inside_transaction?
to Gitlab::Database.inside_transaction? Since this change is required
by different changes which may not arrive in sequence, it's easier
to extract this change out on it's own.

Fix reports jobs timing out because of cache

Closes gitlab-ee#12021, #60879, and gitlab-ee#11303

See merge request gitlab-org/gitlab-ce!29780

Note: This commit relies on
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26801
which brings support to multiple extends.

While `cache: {}` can disable a cache being set globally, it doesn't
work with extends, which will perform a reverse deep merge based on the
keys.

The cache defined in the base `.default-cache` job
won't be disabled in the report jobs.

As a side effect, the `code_quality`, `sast`, and `dependency_scanning`
jobs are running on a larger code base than expected, leading to
timeouts.
