[phpstorm-stubs] remove Pure attribute on rand functions that can change global state

mt_rand both reads and modifies global RNG state internally.  random_int()/random_bytes() would modify OS-level state. gmp_random_* modify random state in GMP. array_rand, shuffle, str_shuffle are the same. They all effectively call mt_rand() internally and change state
