runtime(yaml): improve syntax highlighting for YAML
- Recognize block scalar style to avoid unexpected highlighting by `yamlFlowString` (fix #11517)
- Improve performance of `yamlFlowMappingKey` by allowing execution by the NFA engine (fix #10730)
- It was intentionally disabled before patterns were optimized by `s:SimplifyToAssumeAllPrintable`.
- Fix detection of flow style mapping indicators (fix #8234).
- Enable highlighting of explicit mapping value indicators and node properties in flow style.
- Add syntax highlighting tests
closes: #14354
