Apply the ruff lint (including pyupgrade) and format fixes for the Python 3.11 target in the following areas: - tools (idf_py_actions, install_util, test_bsasm, test_idf_diag, test_idf_py, test_idf_size) - tools/ci - tools/test_apps - tools/test_build_system - tools/ldgen Findings that are not auto-fixable (long lines, a shadowed builtin, type comparisons) are fixed by hand. Also fix the typos reported by codespell and the mypy error in tools/ci/idf_pytest/utils.py that surfaced once the file was touched, and switch check_for_file_paths.py to the SPDX header (removing it from the copyright ignore list).
