Add button to Security Configuration to enable SAST scanning

See merge request gitlab-org/gitlab!36432

This adds a button to the Security Configuration page, allowing the user
to enable SAST scanning via a merge request with a simple click. This
button is only displayed when:

1. The sast_configuration_by_click feature flag is enabled.
1. The project does not have an existing .gitlab-ci.yml file.

Some other changes include (and are _not_ behind any feature flag):

 -  Add third status text string for when Auto DevOps is enabled.
 -  Add third column headed "Manage" to the Security Configuration
    table, which contains a link to that scanner's documentation. This
    is where the button appears in the SAST case when the
    sast_configuration_by_click feature flag is enabled.
 -  Extract thClass constant in app component.
 -  Do not guard the SASTConfigurationController#create action behind
    the sast_configuration_ui feature flag. This feature flag is
    intended for a future iteration when an actual configuration UI
    exists for SAST, which is what that controller is actually for. In
    this iteration, it's simply a placeholder for the temporary REST
    endpoint, which will be [replaced][gql] by a GraphQL mutation in
    another iteration.

This is an MVC for creating a [Configuration UI for SAST][1]. Some
technical debt has been incurred here:

1. The REST (POST) endpoint used to create the merge request will be
   replaced by a [GraphQL mutation][gql].
1. The `type` of each feature has been added to the security
   configuration features exposed to the fronted. This should be
   [replaced][type] by a field exposing the scanner's configuration UI
   path (or similar).
1. The CreateMergeRequestButton component will likely be removed in the
   next iteration of the SAST Configuration UI, particularly if the
   GraphQL mutation is ready by then.
