Fix pdf.js rendering pages in the wrong order

Replace peek-pg with our own implementation

Closes #44441

See merge request gitlab-org/gitlab-ce!31187

Instead of complicated splicing, we can simply return all pages.
Promise.all will take care of the correct ordering for us.

Resolve "Support runtime Visual Review configuration"

See merge request gitlab-org/gitlab-ce!30481

* adds the ability to enter a merge request ID directly into the toolbar,
* adds the option to save the ID to `localStorage` (as with the token),
* adds a link to change the ID once entered
* adds some more explanatory errors for 401 & 404
* saves the comment to session storage if the user navigates away without posting it

There was an implicit assumption that the pages returned from the
Promise of `pdf.getPage(num)` would return in order, but no such
guarantee exists. To handle this, we explicitly set which array index
based on the page number and then trigger a Vue update via `splice`.

Further remove `if postgresql?` branches

Closes #65054

See merge request gitlab-org/gitlab-ce!31102

This ensures this spec is the same in both CE and EE.

This changes the spec in question so that it is the same for both CE and
EE. This requires an `if Gitlab.ee?` since EE requires that we stub an
EE specific module, but doing so in CE will break the spec there.

This changes a protected tags feature spec so that it is the same in
both CE and EE. This requires the use of a `if Gitlab.ee?` check, as the
added lines don't work in CE but do work in EE. Removing them entirely
in turn breaks the EE spec.

This ensures that both CE and EE have the same specs.

This backports two EE specific changes made to the schema changes. We do
not yet backport the EE prepend, as this will/can be done when
https://gitlab.com/gitlab-org/gitlab-ce/issues/58170 is implemented.

This backport changes made by EE to the files in the scripts/ directory.
This comes with a few changes to some scripts to make them work in the
single codebase setup.
