A new programming example of vecadd using sharding

This is re-check in a previously reverted PR.

2. Host create sharded buffer on L1 directly.
3. Host write vector a and b to L1 sharded buffer, read c from L1 to host. No read and write kernel is needed. Only compute kernel.
4. cb buffer points to L1 buffer address with global address.
