Create eslint-plugin-eui-a11y plugin (#215859)
## Summary

This adds an additional custom ESLint rule package which checks certain
Eui elements for the existence of an `aria-label` prop.

If it exists, it will leave it untouched. If it doesn't, it will warn
the engineer it needs to be added, and offers a autofix suggestion for
those engineers who have fix on save enabled in their IDE.

This package is an offshoot of the `kbn-eslint-plugin-i18n` and
`kbn-eslint-plugin-telemetry` packages.
