Add non-nested generic report types to GraphQL finding modal

What does this MR do and why?

Adds the remaining (non-nested) generic report types to the new, GraphQL version of the finding modal:

• ModuleLocation
• Commit
• Text
• Markdown
• Boolean
• Int

It also includes a small refactor that moves the GraphQL-type -> component map out of a shared constants file.

How to set up and validate locally

Setup

1. Have the related FF enabled: echo "Feature.enable(:pipeline_security_dashboard_graphql)" | rails c
2. You'll need an EE License
3. You'll need to have runners enabled (See $2408961 for setting up a runner)
4. Import https://gitlab.com/gitlab-examples/security/security-reports
5. Run a pipeline on master

Validation

1. Go to the pipeline's security report tab
2. Click on the finding with the title "X-Frame-Options Header Not Set"
3. Verify that all the fields render as-expected

Note: The current test data only renders a subset of types, but once the list and table types are rendered, we should have a full picture.
