YQL-19616: Generate YQLs syntax highlighting

- Support `Before` at core `TRegexPattern` and `IGenericLexer`.
- Added `Name` and `Extension` to core `THighlighting`.
- Added `Tighlighting` for `YQLs` factory method.
- Added `--language` option to `yql_highlight`.
- Added `artifact` targets for `YQLs`.

Yes, using the `NSQLTranslation::THighlighting` for
`YQLs` is not correct, but much simplier than generalize
this infrastructure just for a `YQLs`. So here is a
trade-off between development time and a clean code.
