a4641c8b - threading: improve safety posture of modifying global bindings (#35761)

threading: improve safety posture of modifying global bindings (#35761) Ensures that we are holding some lock (a new one) while mutating the internal global `jl_current_modules` table. While reading these binding values is not memory-safe to do simultaneously (it may invent pointers from thin-air and segfault), this commit ensures that a data conflict during the writes to them will not corrupt the values written into memory.
