* [Enhancement] Add zero initialization option to GEMM operations

- Introduced a new `zero_init` parameter to the GEMM function, allowing for optional zero initialization of the accumulator.
- Updated the GEMM implementation across various CUDA architectures to support the new parameter.
- Modified the Python interface for GEMM to include the `zero_init` argument, enhancing flexibility in kernel execution.
- Ensured compatibility with existing functionality while improving initialization control for performance optimization.

* rename zero_init to clear_accum

* lint
