#63288) Add --provider and --providers-json flags to extract_parameters.py and extract_connections.py so each backfill run uses an isolated temp providers.json and only scans the target provider. In --provider mode, modules.json is not written (it would be incomplete), so concurrent runs don't clobber each other. The backfill command now creates a TemporaryDirectory with per-version providers.json files instead of patching a shared file. (cherry picked from commit a9c0bf3)

Cherry-pick of #63288 for the Airflow 3.2.2 patch release.
Backported as a prerequisite for the `breeze registry` tooling chain that ultimately enables #66311 (Breeze `down` discovery). #63288 introduces the `@option_python` decorator on `registry backfill` and the parallel-backfill plumbing that downstream PRs (#65223, #65972, #65984, #66311) build on.
