libservo: Improve finding python (#33385)
* libservo: Improve finding python

Servo is built in a virtual environment, which sets `VIRTUAL_ENV` to
the base path of the venv.
PYTHON3 is only set if mach or the user set it.

Additional changes:

- Use Path / var_os for Paths instead of strings.
 In General using Path APIs is preferable, since in rare cases
 valid paths may not be valid utf-8.
- Don't search for python 3.8 anymore, since
  we require a newer version anyway.
- Don't add the .exe suffix anymore, since
  Command::new() will take care of that.

* Fix finding venv python on windows

- On Windows the venv scripts and python binaries are in the
  `Scripts` subdirectory instead of `bin`.
- We shouldn't check if the executable in the venv binary dir
  exists, since the actual file could have a `.exe` suffix.
  We don't need to consider the `.exe` suffix for the filename,
  since `Command` will handle that for us.
  We also anyway check the validity of the candidate file, by
  running `$candidate --version`.

The Servo Parallel Browser Engine Project

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, and Android.

Servo welcomes contribution from everyone. Check out The Servo Book to get started, or go to servo.org for news and guides.

Getting started

For more detailed build instructions, see the Servo book under Setting up your environment, Building Servo, and Building for Android.

macOS

  • Download and install python, Xcode, and brew
  • Install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  • Restart your shell to make sure cargo is available
  • Install the other dependencies: ./mach bootstrap
  • Build servoshell: ./mach build

Linux

  • Install curl and python:
    • Arch: sudo pacman -S --needed curl python python-pip
    • Debian, Ubuntu: sudo apt install curl python3-pip python3-venv
    • Fedora: sudo dnf install curl python3 python3-pip python3-devel
