…g to info so they persist when dismissed (elastic#84904)

**Addresses:** elastic#76587

## Summary

In this PR I'm doing basically 2 things:

1. Making readonly callouts we have in Detections `primary` instead of `warning` and thus persistable in local storage (if a callout is dismissed, we remember it there)
2. Creating a reusable implementation for that.

TODO:

- [x] Adjust all callouts used in Detections to be of type `primary`
- [x] Implement the local storage logic (dumb)
- [x] Implement the local storage logic (reusable)
- [x] Add a new user role: "Reader" (read-only user)
- [x] Add Cypress tests

Out of scope:

- Add unit tests. I'll probably address this in a follow-up PR. Do you think it's worth it or better to wait until the rework (see the next point)?
- Rework callouts to standardise them across Detections, Cases and other parts of the Security app? See my comment below in this PR.

## Screen recordings

Quick demo of how this implementation works:

- [primary callouts](https://drive.google.com/file/d/1SYQd_ihKPvzlVUxELI8qNEqLBOkL18Gd/view?usp=sharing)
- [warning, danger](https://drive.google.com/file/d/1lrAFPyXNjOYSiEsUXxY_fjXsvmyDcdWY/view?usp=sharing) (callout types here were manually adjusted)

## Additional notes

Cypress tests are based on the work done in elastic#81866.
