Extend setup cmake ability (#3349)

Summary:
For executorch users, we see a common pattern that they have to:

```bash
bash install_requirements.sh --pybind xnnpack

cmake -S . -Bcmake-out ...

cmake --build ...
```

This is repeating cmake build twice, the first one is inside setup.py.

Here I'm adding a way to allow setup.py to install the libraries seperately, by passing `CMAKE_ARGS` and `CMAKE_BUILD_ARGS` into setup.py, through `install_requirements.sh`.

After this change, user can do:

```bash
export CMAKE_ARGS="-DCMAKE_INSTALL_PREFIX=<install dir> \
  -DEXECUTORCH_BUILD_OPTIMIZED=ON \
  ..."

export CMAKE_BUILD_ARGS="--target install"

bash install_requirements.sh --pybind xnnpack
```

Then we should be able to find `libxnnpack.a` `liboptimized_ops_lib.a` etc under install dir.
