Remove all clang tidy warnings from the core library of Lethe (chaos-polymtl#1243)

Description
Since I have deployed the new CI action, we are able to identify many more alerts using clang sanitizer. This PR aims at removing the alerts from the core library of Lethe. We still have warnings when we compile with clang, but this will need an additional CI instance check.

Testing
All units tests and application tests should pass before this is merged.
