wp_generate_uuid4 collisions

It seems like wp_generate_uuid4() is prone to creating UUID collisions, since it internally uses mt_rand, which uses a 32-bit seed. When this seed repeats, it will generate the same UUID twice. Maybe it should be updated to use wp_rand instead which uses random_int so it's backed by a real CSPRNG?
