Revert "zmake: Use vpython3 in cmake"
This reverts commit 338b2fa082a886c6134ca67586d38a83bd49fe6a.
Reason for revert: Breaks in emerge.
Original change's description:
> zmake: Use vpython3 in cmake
>
> Add cmake variable to force it to use vpython3 instead of auto-detecting
> the path to python. This is slightly fragile due to logic in
> zephyr/main/cmake/modules/python.cmake. You can pass in PYTHON_PREFER
> but it will extract the version from that binary and run
> /usr/bin/python${ver}, which is very strange. Pass Python3_EXECUTABLE
> to bypass all of that logic, but it has to be exactly the version in
> PYTHON_MINIMUM_REQUIRED or it will fail. We'll need to make sure we keep
> the vpython version matched with PYTHON_MINIMUM_REQUIRED in the future.
>
> Update the instructions to run ram_report because it works inside the
> chroot now.
>
> Added some missing packages to twister_launcher.py as well. I'm not sure
> why this change made them start to be required, but they are.
