[cmake] End support for python3.5 for pytorch (#43105)
Summary:
PyTorch uses f-string in its python codes.
Python support for f-string started with version 3.6
Using python version 3.5 or older fails the build with latest release/master.
This patch checks the version of the python used for build and mandates it to be 3.6 or higher.
