cleanup(tools.func): remove 22 unused functions (~546 lines dead code)

Removed functions with 0 external callers:
- get_default_php_version, get_default_python_version, get_default_nodejs_version
- is_apt_locked, wait_for_apt
- start_timer, end_timer (was also buggy - silent)
- verify_gpg_fingerprint
- hold_package_version, unhold_package_version
- get_parallel_jobs
- enable_and_start_service, is_service_enabled, is_service_running
- should_upgrade
- verify_package_source, is_lts_version
- download_with_progress
- curl_api_with_retry
- get_cached_version (write-only cache - never read)
- setup_local_ip_helper
- get_latest_gitlab_release
