This commit enables offloading of R.matmul + R.dequantize to cuBLAS codegen. Dequantization scale is passed to runtime function and set to alpha parameter. If there is no dequantization, then alpha == 1.0.

This commit enables offloading of
R.matmul+R.dequantizeto cuBLAS codegen. Dequantization scale is passed to runtime function and set to alpha parameter. If there is no dequantization, then alpha == 1.0.Also, it can be used to fuse output scale to matmul in case of FP8.
