refactor!: consolidate config

- Move config into separate file
- Deprecate `bold_vert_split` in favor of `highlight_groups = { VertSplit = { fg = 'highlight_med', bg = 'highlight_med' } }`
- Deprecate `dim_nc_background` in favor of `highlight_groups = { NormalNC = { fg = 'text', bg = 'surface' } }`
