Enable ONNX_ML by default (onnx#1810)

* Enable ONNX_ML by default

Apparently, official wheel packages enable it. However, if a
user builds ONNX by herself/himself, ONNX_ML will be disabled
by default. For example, as of writing, ONNX does not have a
wheel package for Python 3.7 and users need to build ONNX.

* Disable ONNX_ML for PyTorch

* Honor ONNX_ML in an environment variable

* Fix the condition for ONNX_ML in gen_doc.py

* Revert a permission change
