Although the block size of input/output MXFP tensors is already checked by the block_scaled type, I believe we're missing a check in the verifier for start:
```
ERROR_IF(is_block_scale<in_out_t>() &&
         start[rank(shape1) - 1] % get_innermost_block_size<in_out_t>() != 0);
```
I suspect dynamic input/output tensors could be used to trigger error_if in the verifier once implemented.
