neovim: update multiple

- nvim-ts-rainbow: move config into 'nvim-treesitter.configs' block
- bufferline.nvim: update lsp diagnostic display, highlight
- gitsigns.nvim: add highlight for line blame info
- nvim-autopairs: update new config
- highlight: no more lazy loading (only 1-2ms faster, and caused some
  glitched highlights at startup due to treesitter group)
- chore: theme.util -> util
