lalala-sh 35231e98e8 [CK] use int64 for ptr offset (#5094) ...

## Motivation

When the number of experts (E) is large (e.g., E=257 in DeepSeek-V3),
the `expert_id * expert_stride` calculation in MOE GEMM kernels
overflows `int32` (`index_t`), causing the weight matrix (B) pointer to
wrap to an invalid address and triggering a GPU memory access fault.

For example, with `N=1024, K=7168, IsInputGemm=true`:
- `expert_stride = N * K * 2 = 14,680,064`
- `INT32_MAX / expert_stride ≈ 146`
- Any `expert_id >= 147` causes overflow → negative offset → illegal
memory access → GPU crash
