Revisit how the Android port works.
Fix#20855Fix#18625Fix#21147
Before polishing and making sure everything works fine (like the VR code, the android-x86 version, the non-android version of the lib, …), I'd like to get some early feedback on the approach.
I recommend reviewing commit by commit.
To test, just follow the regular steps:
```
./mach build -d --android
./mach package --dev --android builds servo.apk
./mach install --dev --android && ./mach run --android
```

Change to pip dependency install invocation during virtualenv setup in build
<!-- Please describe your changes on the following line: -->
Fix for https://github.com/servo/servo/issues/20990
In short, the pip invocation was causing my build on OSX to break. Using `python -m pip` in place of `pip` when setting up the virtual environment fixes the environment setup failure and allows the build to proceed.

The sys.platform check in need_pip_upgrade was doing effectively the same pip invocation regardless of what
platform we were evaluating to.
Additionally, removed some duplicate definitions of the python variable which was already in scope
higher up in the function.
