Add mode specific styles (#2676)

* Add mode specific styles

In similar vein to neovim's lualine and similar statusline packages this
allows helix users to style their mode based on which mode it is thus
making each mode more visually distinct at a glance

* Add an example based on rosepine

* Add editor.colors-mode config

* Document statusline mode styles
