Switch the dimensions array to use uint32_t instead of size_t.

size_t isn't safe, since we pack/unpack the array as a 32-bit int array, but
that is the wrong type for 64-bit. Switching to uint32_t is better, since we
only support 1 dimension today, and won't need many more than that even for
complex cases in the future.
