This PR adds property support to Torchbind. There are two cases that it needs to work:
**Torchscript**
Inside Torchscript, we don't go through pybind so there is no issue with accessing properties through ClassType.
**Eager Mode**
In Eager Mode, Torchbind creates ScriptObject which we cannot dynamically add (aka access) properties after initializing it. (https://stackoverflow.com/questions/1325673/how-to-add-property-to-a-class-dynamically
) Therefore we created a Python wrapper (ScriptObjectWrapper) around ScriptObject where we can use property method to set properties. By doing so, we can look up wrapped object's property through __getattr__ method of the ScriptObjectWrapper. This logic is inspired from https://github.com/pytorch/pytorch/pull/44324

**Summary**
This commit adds support for static methods to TorchBind. Just like
pybind, the API for declaring a static method is `def_static(...)`. A
static method must be called on the class directly, and can be called
both in Python as well as TorchScript.
Support for static methods is implemented in a manner similar to that of
instance methods. Registered static functions are wrapped in a layer of
unboxing logic, their schemas are inferred using templates and
metaprogramming, and they are added to the `ClassType` object
corresponding to the TorchBind class on which they are registered.
ScriptClass has been extended to support a `__getattr__` function so
that static methods of TorchBind classes can be invoked in Python. The
implementation of `__getattr__` returns `ScriptClassFunctionPtr`, a
version of `StrongFunctionPtr` without a compilation unit (since the
functions of a TorchBind class live inside the TorchBind registry).
Within TorchScript, TorchBind static functions are desugared in
`PythonClassValue::attr` by looking them up on the class type of the
`PythonClassValue` instance.
**Test Plan**
This commit adds a unit test that tests a simple static method on a
TorchBind class.
