Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times

Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return
warnings, but don't enable them. While the warnings can be useful, they
are in general too noisy to enable.
