[ci] Add node scripts/yarn_deduplicate check (#169165)

- Adds an entrypoint, `node scripts/yarn_deduplicate` for fixing
duplicated packages via npm package `yarn-deduplicate`
- Fixes existing duplicated packages
- Adds a CI check verifying no duplicated packages have been added.  

There are currently two exclusions - all types packages which causes
other checks to break, and axe-core, which does not follow semver.

Closes https://github.com/elastic/kibana/issues/125712
