utils: framework builder

[FeelyChau]

We have built some framework packages for the example pipelines, I think it's time to implement the framework maker to help the users to make it themself.

First, we should define the format of the framework description file, maybe as follows:

{
  "name": "tfjs",
  "version": "3.8.0",
  "type": "js",
  "packages": [
    {
      "name": "@tensorflow/tfjs-node",
      "version": "3.8.0",
      "type": "js"
    },
    {
      "name": "tensorflow",
      "version": "2.6",
      "type": "python"
    }
  ]
}

The file name should be framework.json. We could run the command in the directory:

$ pipcook framework make .

Then the maker should download the node.js package@tensorflow/[email protected] into the node_modules in the framework directory and download the python package tensorflow into directory site-packages.
After running the maker in every environment(the matrix of Linux/macOS/windows and node v12.17/v12.19/v12.22/v14.0/v14.12/v14.17), all frame packages suitable for these environments could be made.
