Fix n plus one issue ci build dast profile

What does this MR do and why?

As described in #346325 (closed), there are two N+1 issues when multiple builds with the dast_configuration keyword are present in the YAML file.

Example:

stages:
  - dast
dast:
  stage: dast
  dast_configuration:
    site_profile: dast_site_profile_name
    scanner_profile: dast_scanner_profile_name
  script:
    - exit 0
dast2:
  stage: dast
  dast_configuration:
    site_profile: another_dast_site_profile_name
    scanner_profile: another_dast_scanner_profile_name
  script:
    - exit 0

In order to fix these N+1 issues this Merge Request:

• Creates a service that takes several builds and profiles and associates them inside a single database insert.
• Extends the profiles finder to batch load profiles.
