[ML] Consolidate redundant time_buckets into @kbn/ml-time-buckets.

[walterra]

Summary

Follow up to #46227.

Consolidates multiple copies of time_buckets.js into @kbn/ml-time-buckets. The scope of this PR is just to consolidate the files. In follow ups we still need to: Refactor JS to TS and get rid of the code that uses this using "dependency cache" in the ml plugin.

Checklist

• Unit or functional tests were updated or added to match the most common scenarios

This file will be removed via #178566
but good catch on creating a separate file for getTimeBucketsFromCache for settings.ts which still uses it 👍

[walterra]

Good to know, let's get yours in first and then see if I get any conflicts with this one.

[alvarezmelissa87]

Code LGTM - will give it a test tomorrow and update. Nice piece of work! 🙏

Tested the following and functionally had no issues:

• Anomaly detection creation and explorer
• Anomaly detection embeddables in Dashboard
• File upload
• Index data visualizer
• Change point detection

Code also LGTM 🎉
