Peter Dillinger befa6b8050 Fix and check for potential ODR violations (#14096)
Summary:
... caused by public headers depending on build parameters (macro definitions). This change also adds a check under 'make check-headers' (already in CI) looking for potential future violations.

I've audited the uses of '#if' in public headers and either
* Eliminated them
* Systematically excluded them because they are intentional or similar (details in comments in check-public-header.sh
* Manually excluded them as being ODR-SAFE

In the case of ROCKSDB_USING_THREAD_STATUS, there was no good reason for this to appear in public headers so I've replaced it with a static bool ThreadStatus::kEnabled. I considered getting rid of the ability to disable this code but some relatively recent PRs have been submitted for fixing that case. I've added a release note and updated one of the CI jobs to use this build configuration. (I didn't want to combine with some jobs like no_compression and status_checked because the interaction might limit what is checked.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/14096

Test Plan: manual 'make check-headers' + manual cmake as in new CI config + CI
