[Security Solution][Explore] Migrate from styled-components in shared (…

…elastic#210311)

Addresses elastic#206436

- Replace styled-components with @emotion/react and @emotion/styled
across multiple components
- Remove `@kbn/ui-theme` instances
- Update test cases to use @emotion/jest matchers for toHaveStyleRule to
work properly
- Adjust styles to use `css` from `@emotion/react`
- Remove unused imports and updated snapshots
