Extend Actions in Scan Execution Policy to include Runner Tags

What does this MR do and why?

With https://docs.gitlab.com/ee/ci/runners/configure_runners.html#use-tags-to-control-which-jobs-a-runner-can-run you can select tags for each job in your .gitlab-ci.yml file. These tags allows to control which jobs a runner can run.

With this feature we want to add this functionality to GitLab and extend Scan Execution Policy with information about tags.

You can read more about this in Allow Users to Define Tags for Scan Execution P... (&9176 - closed).

How to set up and validate locally

1. Add tags (eg: Security Policy) to a runner from Admin -> Runners -> Edit
2. Create a scan execution policy from Security & Compliance -> Policies

scan_execution_policy:
- name: Scan Execution Policy
  description: ''
  enabled: true
  rules:
  - type: pipeline
    branches:
    - "*"
  actions:
  - scan: container_scanning
    tags:
    - Security Policy
  - scan: secret_detection

3. Run a pipeline on any of the branches and verify if the scan job has tags applied and picked by the runner with specified tag
