Error message: ScaledMatmul custom call batch dimension mismatch.

The __op$block_scaled_dot custom call performs batched matrix multiplication on MXFP8-quantized tensors. When the LHS and RHS specify the same number of batch dimensions, the compiler compares the products of their batch dimension sizes and raises this error if the products differ.

To fix this error, ensure the product of LHS and RHS batch dimension sizes match.
