python whl package build support status

• windows build (not ok)
• linux build (ok, cpu or gpu)
• macos build (ok,cpu only)

build env prepare

linux

```
1: enable rootless docker env, refs: https://docs.docker.com/engine/security/rootless/
2: cd ./scripts/whl/linux/manylinux2010
3: ./build_image.sh cpu
4: ./build_image.sh cuda

```

macos

```
./scripts/whl/macos/macos_whl_env_prepare.sh
```

how to build

build for linux

MegBrain delivers `wheel` package with `manylinux2010` tag defined in [PEP-571](https://www.python.org/dev/peps/pep-0571/).

```
./build_wheel.sh cpu

CUDA_ROOT_DIR=/path/to/cuda \
CUDNN_ROOT_DIR=/path/to/cudnn \
TENSORRT_ROOT_DIR=/path/to/tensorrt \
./build_wheel.sh cuda
```

And you can find all of the outputs in `output` directory.

If you just want to build for a specific Python verison, you can use `ALL_PYTHON` environment variable. eg:

```
ALL_PYTHON=35m ./build_wheel.sh cpu

```

build for macos

```
./scripts/whl/macos/macos_build_whl.sh
```
