[CI Problem] [docker] Pip package installation in cortexm image

[mehrdadh]

Using any other docker image we can easily install extra packages by running a command: sudo pip3 install XX
and then it would be available in the python environment.

However, in Cortexm image installing the package with sudo pip3 install or pip3 install --user would end up in a different python env. My guess is because of this line that we have for cortexm and riscv images:

i was able to solve this by adding a dedicated venv group. i'll roll that into my venv PR

I tested the hexagon docker image, the issue still exists. Perhaps the issue is related to user not having permission on python packages installation path

With tvm-venv used in tvm dockers, you can enter the virtual env and pip install packages. So this issue is resolved.
