Error text overflow

Pull Request

🤨 Rationale

Fixes #2431

👩‍💻 Implementation

Updated the error pattern to be a mixin rather than an interface so that controls using the error pattern don't have to redefine the properties/attributes that the pattern uses. Additionally, logic has been added to the mixin (beyond what the interface supported) to use the overflow behavior to add a title to the error text when it overflows.

🧪 Testing

Manually tested in storybook that all updated components:

• don't have a title on the error text when the error text is short
• have a title on the error text when the error text overflows
• the overflow on the error text does not affect any existing overflow behavior on the component

New unit tests for the error pattern mixin

✅ Checklist

• I have updated the project documentation to reflect my changes or determined no changes are needed.

@m-akinc, will you buddy this PR for me?

Seems relatively straightforward so I'm ok with this going in before @rajsite approves
