infra_virtualenv: Introduce python_venv.

This change will introduce a new script `python_venv` which
transparently executes a Python interpreter in a virtualenv,
possibly creating a new virtualenv if it has not been created
yet.

This script is a better replacement to `find_virtualenv.sh`
because:

1. `python_venv` does not require to be sourced from bash.
   This allows any program (e.g. Python) to run a Python
   interpreter in a virtualenv. Also it makes it easy to run
   an interactive Python shell in a virtualenv, which is
   convenient to manually inspect the virtualenv environment
   for debug.

2. `python_venv` can be called from any working directory,
   which makes the caller code simpler.
