fix: remove style modifying all host components with hidden attribute (#7346)

**Related Issue:** #7325

## Summary

- Removes style modifying all host components with hidden attribute.
This is modifying components outside of calcite and applying host styles
outside of the host. Host styles should have no effect outside of a
shadow DOM. https://developer.mozilla.org/en-US/docs/Web/CSS/:host
- Adds includes mixin for common component internal styles such as
hidden attribute styling
- Includes mixin in every component file.
