feat(toolchains): support runtime registration from manifest (#3802)

Currently, all supported Python runtime versions and their
platform-specific metadata (URLs, SHA256s, strip_prefix) must be
hardcoded in `python/versions.bzl`. This makes it slow and difficult
to adopt new Python versions or custom builds without updating
`rules_python` itself.

This PR introduces the ability to dynamically fetch and register
Python runtimes from a remote python-build-standalone (PBS) manifest
file (e.g., `SHA256SUMS`).

This is supported via two new attributes in `python.override`:
- `add_runtime_manifest_urls`: A list of URLs pointing to manifest
  files  to parse and register.
- `runtime_manifest_sha`: The SHA256 hash of the manifest file.

The manifest file format is the python-build-standalone SHA256SUMS
format (`SHA FILENAME`), extended to allow arbitrary URLs for the
filename (to allow more arbitrary locations).
