Before this change, every generated boxed kernel wrapper unpacked its
EValue stack args via the abort-on-mismatch accessors (.to<T>(),
.toOptional<T>(), .toTensorList(), .toIntList(), .toDoubleList(),
.toBoolList(), .toListOptionalTensor()). A malformed PTE whose
KernelCall arg_indices point at wrong-tagged EValues would therefore
crash the runtime with ET_CHECK_MSG inside the generated wrapper,
before the underlying native kernel sees the inputs.
Emit the Result-returning tryTo* counterparts instead, with a single
shared error-propagation pattern:
auto x_res = ev.tryTo<T>();
if (!x_res.ok()) { context.fail(x_res.error()); return; }
T x = x_res.get();
The kernel entry function is already void-returning and takes a
KernelRuntimeContext&, which has a documented fail() channel for
precisely this case — no ABI change, no signature change, no impact
on hand-written kernels registered directly against OpFunction.
Coverage: _gen_code_base_type, _gen_code_optional_type, and each
typed branch of _gen_code_list_type (Tensor, int/SymInt, float, bool
with ATen/lean variants, and ListOptional<Tensor> with ATen/lean
variants).
Depends on the EValue::tryTo<T>() API added earlier in the stack.
