[EuiCallOut] Add dismissButtonProps

[acstll]

Summary

This PR enables adding data attributes to the dismiss button in EuiCallOut.

It introduces the dismissButtonProps prop, following a common pattern in the library.

Note

This PR also introduces a DataAttributeProps interface to ensure TypeScript is happy about data-* attributes — it's deliberate to have it separate from the already existing CommonProps —— it's also deliberate to use it only in dismissButtonProps for now

Why are we making this change?

To fulfill a request.

Impact to users

🟢 No impact. It's a new prop.
