f07f3d9d - Support id() on containers and copy.deepcopy tracing (#177484)

Support id() on containers and copy.deepcopy tracing (#177484) Summary: Allow dynamo to trace through stdlib copy.deepcopy by removing the copy module from BUILTIN_SKIPLIST and copy.deepcopy from _builtin_function_ids. Dynamo now inlines the Python implementation of deepcopy, which works for constant containers (dicts, lists, tuples). For tensors, __deepcopy__ triggers a graph break since FakeTensors cannot be deep-copied. To support id() on ConstDictVariable, ListVariable, TupleVariable, ConstantVariable, SymNodeVariable, and SetVariable, introduce FakeIdVariable — a compile-time-only variable that holds id(vt) and can participate as a dict key but intentionally blocks reconstruction across graph breaks to prevent silently baking stale ids into resumed bytecode.
