Mengwei Liu b5cd4ac950 [torchgen] Add support for schema with namespace (#148038)
Fixes https://github.com/pytorch/executorch/issues/8711

In ExecuTorch when we try to parse the following schema:

```
aten::__lshift__.Scalar(Tensor self, Scalar other) -> Tensor
```
Repro:

```python
from torchgen.model import FunctionSchema
native_schema = FunctionSchema.parse("aten::__lshift__.Scalar(Tensor self, Scalar other) -> Tensor")
```
It's failing because `BaseOperatorName` categorizes it to be a
inplace operator.

I understand we are not supposed to pass in namespace "aten::" into
`FunctionSchema.parse()` but unfortunately ExecuTorch requires this
feature to work.

This PR adds a new `namespace` attribute to `BaseOperatorName` and makes
sure the rest of the stack works as before, if a schema without
namespace  is passed in

This folder contains a number of scripts which are used as part of the PyTorch build process. This directory also doubles as a Python module hierarchy (thus the __init__.py).

Overview

Modern infrastructure:

  • autograd - Code generation for autograd. This includes definitions of all our derivatives.
  • jit - Code generation for JIT
  • shared - Generic infrastructure that scripts in tools may find useful.
    • module_loader.py - Makes it easier to import arbitrary Python files in a script, without having to add them to the PYTHONPATH first.

Build system pieces:

  • setup_helpers - Helper code for searching for third-party dependencies on the user system.
  • build_pytorch_libs.py - cross-platform script that builds all of the constituent libraries of PyTorch, but not the PyTorch Python extension itself.
  • build_libtorch.py - Script for building libtorch, a standalone C++ library without Python support. This build script is tested in CI.

Developer tools which you might find useful:

Important if you want to run on AMD GPU:

  • amd_build - HIPify scripts, for transpiling CUDA into AMD HIP. Right now, PyTorch and Caffe2 share logic for how to do this transpilation, but have separate entry-points for transpiling either PyTorch or Caffe2 code.
    • build_amd.py - Top-level entry point for HIPifying our codebase.

Tools which are only situationally useful:
