Add limit for wiki page content size

See merge request gitlab-org/gitlab!36729

This adds a new validation to restrict the maximum size of a wiki page,
which is only enforced when the content is updated, and only when using
the GitLab UI or API (not for Git pushes yet).

The default limit is 50MB, and can be changed through the Rails console
or the API.
