Frantisek Hrbata 4c90790cd2 fix: ensure the constraint file is followed also for setuptools 
Currently, when the venv is installed or updated, we attempt to
automatically update pip and setuptools within the venv. Unfortunately,
the setuptools package is installed or updated without adhering to the
constraints file, which restricts the setuptools version due to
https://github.com/pypa/setuptools/issues/4480. Resolve this issue by
applying the constraints file to the installation and update of both pip
and setuptools.

# This script helps installing tools required to use the ESP-IDF, and updating PATH
# to use the installed tools. It can also create a Python virtual environment,
# and install Python requirements into it.
# It does not install OS dependencies. It does install tools such as the Xtensa
# GCC toolchain and ESP32 ULP coprocessor toolchain.
#
# By default, downloaded tools will be installed under $HOME/.espressif directory
# (%USERPROFILE%/.espressif on Windows). This path can be modified by setting
# IDF_TOOLS_PATH variable prior to running this tool.
#
# Users do not need to interact with this script directly. In IDF root directory,
# install.sh (.bat) and export.sh (.bat) scripts are provided to invoke this script.
#
# Usage:
#
# * To install the tools, run `idf_tools.py install`.
#
# * To install the Python environment, run `idf_tools.py install-python-env`.
#
# * To start using the tools, run `eval "$(idf_tools.py export)"` — this will update
# the PATH to point to the installed tools and set up other environment variables
# needed by the tools.
