In this PR, I added support for packaging the AOTI generated files into a zipfile, and loading it in python.
`compile_so` takes the path to the package, a device, and a desired so_path location, and compiles package into a .so, and saves to the specified location.
`load_package` takes a path to the package and device, calls _extract_so, and then creates a callable to run the compiled model.
The zipfile generated looks like the following:
```
|- version
|- archive_format
|- data
|- aotinductor
|- cbtnafqaqrhvwztv7xudlal4xs6sofxa5oxccyuaqtrt6aozaklx.cubin # AOTI cuda generated cubin files
|- cskkqtna23bty2v3aq7g2q37cxrgufehlkuaaolhlgug5zg6fuwe.cpp # AOTI generated cpp file
|- cskkqtna23bty2v3aq7g2q37cxrgufehlkuaaolhlgug5zg6fuwe_compile_flags # Flags for compiling the .o
|- c6qqtnpgwfi3dv5nb76ai773kt45ezoxfwdmd7q37lvq6fs2tnoi.o # AOTI saved const.o
|- cskkqtna23bty2v3aq7g2q37cxrgufehlkuaaolhlgug5zg6fuwe_linker_flags # Flags for linking the files to form the .so
|- constants
|- constants.pt # Constants saved using torch.save, can be loaded using mmap
```
The workflow is something like:
```
with torch.no_grad():
ep = torch.export.export(
model,
example_inputs,
dynamic_shapes=dynamic_shapes,
strict=False,
)
gm = ep.module()
package_path = torch._inductor.aot_compile(
gm,
example_inputs,
options= {
"aot_inductor.output_path": "my_path.pt2", # or a directory
"aot_inductor.package": True,
}
)
compiled_model = torch._inductor.package.load_package(package_path, device)
return compiled_model
```
I tried turning on loading the weights using mmap by default, but had some trouble with it, so that is just left as a todo

Note [TH abstraction violation] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ TH/THC provide some hpp headers, which are proper C++ headers rather than C headers. These headers serve double duty as *internal implementation detail* headers, whose contents should largely not be used by external clients. Ideally, we would not install these headers at all; instead, you should use public functions (in headers like `THTensor.h`, NOT `THTensor.hpp`) to manipulate these structs. However, there are a few places in torch/csrc where we violate this abstraction. They are marked with a pointer to this note. Each of those sites will have to be refactored when we refactor the guts of THTensor and related structures.
