* Add FP8 scale support and fix alignment for grouped GEMM

- Add FP8 scale_inv pointer handling in nvte_grouped_gemm for proper FP8 GEMM
- Fix random padding in tests to ensure 16-byte alignment for all dtypes
- Reorder GroupedGemmSetupWorkspace members for natural alignment
- Remove debug prints

* Grouped GEMM: code cleanup and NULL C support

- Remove unused alignment parameter from GroupedGemmSetupWorkspace::from_buffers
- Simplify select_grouped_operand by removing dead code branches
- Add GroupedOperandSelection.tensor field to avoid passing tensor separately
- Extract set_fp8_scale_pointers and init_matrix_layouts helpers
- Add safety check for FP8 on Hopper column-wise fallback
- Support NULL C tensor when beta=0 (uses D as placeholder)
- Remove unused get_scale_inv() from test
- Add use_null_c test parameter and test case
- Fix documentation: alpha/beta are single element tensors only
