Apply formatter on recent 45 commits. (#5827)

Browse Source 
Summary:
Some recent commits might not have passed through the formatter. I formatted recent 45 commits. The script hangs for more commits so I stopped there.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/5827

Test Plan: Run all existing tests.

Differential Revision: D17483727
