Kernel: static vs non-static constexpr variables
Problem: - `static` variables consume memory and sometimes are less optimizable. - `static const` variables can be `constexpr`, usually. - `static` function-local variables require an initialization check every time the function is run. Solution: - If a global `static` variable is only used in a single function then move it into the function and make it non-`static` and `constexpr`. - Make all global `static` variables `constexpr` instead of `const`. - Change function-local `static const[expr]` variables to be just `constexpr`.
