Vulnerabilities CSV: Rename "scanner" to "tool"

See merge request gitlab-org/gitlab!68238

Fixes Pipelines' guide page example.

See merge request gitlab-org/gitlab!68494

Some of the logic in `Ci::Minutes::Quota` is only used to determine
whether or not to show CI minutes information in the UI. This commit
refactors and renames that logic to make it more clear that it is being
used only for UI purposes.

Changes were recently made to `Ci::Minutes::Quota` that added methods
that avoided checking `Project#shared_runners_enabled` pending the work
done in this MR. They can now be merged into the existing methods, since
`Quota#enabled?` is no longer checking against `#shared_runners_enabled`

Use UPSERT when storing user mentions

See merge request gitlab-org/gitlab!68433

This commit renames the "Scanner Type" column within the vulnerability
report's exported CSV to "Tool". This will make it consistent
with the rest of the UI.

Changelog: changed
EE: true
MR: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68238

Scheduled secret detection scan for security policy

See merge request gitlab-org/gitlab!67752

Adds a feature flag to the optimization done for store_mentions!

This is needed for the UPSERT to work properly since we're detecting a
unique constraint conflict on [noteable_id, note_id]

Changelog: other

Using UPSERT saves us a query, avoids cases where we get
RecordNotUnique, and removes the use of SAVEPOINT which can cause PG
performance issues.
