Reorganize CircleCI workflows (#9981)

Summary:
Condense down to 8 groups rather than 20+ for ease of browsing
pages like
https://app.circleci.com/pipelines/github/facebook/rocksdb?branch=main&filter=all

Also, run nightly builds at 1AM or 2AM Pacific (depending on daylight
time) rather than 4PM or 5PM Pacific, so that they actually use each
day's landed changes.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9981

Test Plan:
CI
And manually inspected
```
grep -Eo 'build-[^: ]*' .circleci/config.yml | sort | uniq -c | less
```
to ensure I didn't orphan anything
