bug: fallback to Kitty foreground/background colors when Normal highlight is undefined

[mikesmithgh]

When no Normal highlight is defined, we should attempt to fallback to Kitty's foreground and background if they exist.

Currently, we are falling back to hardcoded #ffffff and #000000.

See fallback functions:

local function fg_or_fallback(hl_def)
  local fg = type(hl_def.fg) == 'number' and string.format('#%06x', hl_def.fg) or hl_def.fg
  return hl_def.fg and fg or (vim.o.background == 'dark' and '#ffffff' or '#000000')
end

local function bg_or_fallback(hl_def)
  local bg = type(hl_def.bg) == 'number' and string.format('#%06x', hl_def.bg) or hl_def.bg
  return hl_def.bg and bg or (vim.o.background == 'dark' and '#000000' or '#ffffff')
end

Steps to reproduce:

vim.api.nvim_set_hl(0, 'Normal', {})
