pyenv to uv based python and venv

[coder351]

resolves #240 and #30

UV based python uses optimized build
CONFIG_ARGS = "'--build=x86_64-unknown-linux-gnu' '--host=x86_64-unknown-linux-gnu' '--prefix=/install' '--with-openssl=/tools/deps' '--with-system-expat' '--with-system-libmpdec' '--without-ensurepip' '--with-readline=editline' '--enable-shared' '--enable-optimizations' '--with-lto`

UV based python is set to 3.12.3.
PyQt5 uses prebuilt wheels.

TODOs

• I see uv has the optimizations enabled by default, but can we explicitly enable them so we're not relying on defaults?
• PyQt5: either need a script to build/pull the wheel or build/install in the Docker build again
• final test on device
• openpilot runs
• python, python3, pip, pip3, scons all work in a shell logged in as comma

@adeebshihadeh The remaining Todos and comments are resolved.

PyQt5 needs to be cleaned up still, other than that LGTM

[coder351]

@adeebshihadeh I have the refactored PyQt5 to rebuild each time. The build time was 5mins which includes the docker cache.

pip install does currently not work. ERROR: Could not install packages due to an OSError: [Errno 30] Read-only file system: '/usr/local/venv/lib/python3.12/site-packages/<package_name>.

Customs shims are not loaded properly.

[robin-reckmann]

Also uv does currently not have a shim. I think we should have one if we ever intend to use uv on device.

[coder351]

@robin-reckmann I checked the build logs and compile-pyqt5.sh ran without any errors. I have added back the custom shims export path in userspace/files/profile.

[robin-reckmann]

This one is also not necessary.

[coder351]

done.

@robin-reckmann PR is ready if no other issues or concerns please confirm for @adeebshihadeh.

[adeebshihadeh]

This should've been a straightforward PR, but it's taken a lot of people's time now. Bounty is unlocked, @robin-reckmann you want to pick it up?
