maint(clang-tidy): Bugprone enable checks (#3166)

Browse Source 
* Enable bugprone checks

* Reset delta and massage config

* Start to apply bugprone fixes

* try to fix minor bug

* Fix later

* Fix perfect forwarding bugprone

* Remove nolint

* undo constructor delete

* Fix bugprone-perfect-forwarding again

* Remove TODO

* Add another nolint for bugprone-exception-escape in scoped interpreter

* Fix remaining bugprone errors

* Properly apply bugprone-macro-parantheses

* Redo formatting and remove bugprone nolint

* Add coment and revert more whitespace changes

* Fix typo

* Fix parsing bug

* Add back comma

* Fix clang-tidy issue

* Apply remaining clang-tidy fixes
