zig build: change "-Drelease" to "-Doptimize"

I find myself quite often creating ReleaseSafe builds and putting them to production for certain experiments: - Debug info are for stack traces. An ongoing example where those would help is #14815. - Safety checks would have saved a couple of mine and @kubkon's hours in #15098. This is a breaking change for scripts that make Zig releases -- I will submit another PR to zig-bootstrap and release-cutter after this is merged.
