Kefu Chai 0e3f6186cb build: disable enum-constexpr-conversion
Clang-18 starts to complain when a constexp value is casted to a
enum and the value is out of the range of the enum values. in this
case, boost intentially cast the out-of-range values to the
type to be casted. so silence this warning at this moment.
since `lexical_cast.hpp` is included in multiple places in the
source tree, this warning is disabled globally.

the warning look like:
