Fix multiline params feature and auto-prefix

- Fix FB/function call parameter detection to prevent incorrect # prefixing
- Preserve # prefix when filling multiline params
- Add comma after first parameter and closing bracket on last param line
- Fix Tab navigation to position cursor after :=/=> operators
- Clean up dead code in multiline_params.lua
- Add setup functions for multiline params feature in both scl and scl_lsp
