Disable detect_odr_violation for ASan

Browse source 
There's some unfortunate ODR violations that get dianosed with GCC but not Clang
for static inline constexpr variables defined inside the class body:

template<typename T>
struct static_const
{
    static JSON_INLINE_VARIABLE constexpr T value{};
};

This can be ignored pretty much. There is the same problem for std::piecewise_construct:
