ReinUsesLisp 3f2e605dd1 common/bit_cast: Add function matching std::bit_cast without constexpr
Add a std::bit_cast-like function archiving the same runtime results as
the standard function, without compile time support.

This allows us to use bit_cast while we wait for compiler support, it
can be trivially replaced in the future.
