[WIP][DON'T REVIEW] CLUSTER-BY CLAUSE integration

- user model changes: yes
- storage format changes: no
- interface changes: yes

Details:
The CLUSTER BY clause as a single patch: grammar and desugar rewrite, the distributed k-means runtime, k-means|| initialization, and the cosine metric. Squashed for CI validation only -- the work is under review as the separate changes it is split into.
