Move custom rules to markdownlint-rules and ascii-only: ignore code blocks

- Rename .markdownlint-rules to markdownlint-rules; update paths in configs,
  workflows, Makefile, README, CONTRIBUTING, eslint, package.json, .gitignore.
- ascii-only: skip content inside fenced code blocks by default; add
  allowUnicodeInCodeBlocks and disallowUnicodeInCodeBlockTypes options.
- Update fixtures and expected_errors for ascii-only; adjust rule unit tests
  and Python verifier for new paths.
