LibJS: Define Date constants such that translation units don't copy them

Variables that are constexpr must be delcared inline in the global
namespace to prevent copying them.

The static keyword is meaningless on variables in headers in the global
namespace. Declare the static bigint as extern and define it out-of-line
instead.
