This marks the `bit_cast` helper as `constexpr` and allows the casts implemented with it to also be `constexpr`. This is largely not a functional change, but it enables using the casts in expressions that need to be resolved at compile time as demonstrated with the static asserts in the new tests. --------- Co-authored-by: joaosaffran <126493771+joaosaffran@users.noreply.github.com>
