Mengwei Liu 41865bd8ed [executorch] Add RuntimeContext to generated C++ API Signature (#94570)
Summary:
Pass runtime context all the way to kernel level.

RegisterCodegenUnboxedKernels.cpp:

```
static Operator operators_to_register[] = {
    Operator(
        "aten::add.out",
        [](torch::executor::RuntimeContext & context, EValue** stack) {

            EValue& self = *stack[0];
    	EValue& other = *stack[1];
    	EValue& alpha = *stack[2];
    	EValue& out = *stack[3];
    	const torch::executor::Tensor & self_base = self.to<torch::executor::Tensor>();
    	const torch::executor::Tensor & other_base = other.to<torch::executor::Tensor>();
    	const torch::executor::Scalar & alpha_base = alpha.to<torch::executor::Scalar>();
    	torch::executor::Tensor & out_base = out.to<torch::executor::Tensor>();

            EXECUTORCH_SCOPE_PROF("native_call_add.out");
            torch::executor::aten::add_outf(context, self_base, other_base, alpha_base, out_base);

        }
    ),
}
```

Functions.h
```

// aten::add.out(Tensor self, Tensor other, *, Scalar alpha=1, Tensor(a!) out) -> Tensor(a!)
TORCH_API inline at::Tensor & add_outf(torch::executor::RuntimeContext & context, const at::Tensor & self, const at::Tensor & other, const at::Scalar & alpha, at::Tensor & out) {
    return torch::executor::native::add_out(self, other, alpha, out);
}

```

Test Plan: TBD
