Address PR feedback: force-upgrade llvm-aie, quote SCRIPT_PATH

- env_setup.sh / env_setup.ps1 / build.yml: the mlir-air [aie] extra requires
  llvm-aie without a version pin, so an existing installation will silently
  satisfy the requirement and pip won't bump it to the nightly wheel. Add an
  explicit `pip install --upgrade llvm-aie` step (matching the prior script
  behavior) so llvm-aie always tracks nightly.
- env_setup.sh: quote ${SCRIPT_PATH} inside dirname and the PATH/PYTHONPATH/
  LD_LIBRARY_PATH exports so paths with spaces don't word-split.
