Summary: We had a special case for fixing false positives on constexpr implicitly captured by lambdas. However, we do not report dead stores on constexpr anymore, hence, do not need the special case anymore. Moreover, the special case was not only capturing constexpr in lambdas, but also any variables which type had `const` (see new test `capture_const_bad` which was not being reported before this diff)
