pw_build: Update path and target resolution

- Don't implicitly convert paths and labels in python_runner.py.
- To enable finding target outputs, support explicit resolution with
  the <TARGET_FILE($target)> expression.
- Use the standard GN rebase_path approach to resolve GN paths to
  filesystem paths for scripts. Remove workarounds that are no longer
  necessary.
- Update build files to use rebase_path and <TARGET_FILE(target)>.
- Add tests for python_runner.py.
