Use venv module for PROJECT_VENV building
Currently, if USE_VENV=True, PROJECT_VENVs are initialized using the
tools/build_venv.sh script; this script depends on the virtualenv
module, which is much less commonly available than the built-in venv
module which we already use many places.
This changes the build_venv.sh script to use `python -m venv` instead.
