1. add build phase names
2. emit kmeans log
3. emit errors if both `Dot` and `residual_quantiztion` are used
4. update `tuples_done` by estimated value before insertions
5. update `tuples_done` after insertions are done
6. emit errors if `vchordrq_prewarm` is given a partition index
7. rename `maxsim_ip` to `maxsim`

* encode kmeans progress to build subphase names
* add a new GUC `vchordrq.prererank_filtering` (default to `off`) to
control prererank filtering

This changes default `lists` from `[1000]` to `[]`, and default `probes`
to `10` to ` `.

The default value of `1000/10` is too small for big data and may cause
issues for small data.

`lists = []` implies "clusters are not used, and all data are in the
same set". It's good for small data.

Enable it by `SET vchordrq.allows_skipping_rerank TO on`.

Skip rerank by enabling it and `SET vchordrq.epsilon = 0.0`.

1. rename `max_maxsim_tuples` to `maxsim_refine`; leave it a default
value `0`
2. remove `allows_skipping_rerank`; use estimated distance for vectors
whose distance is not calculated
