feat(ftplugin): set Lua 'omnifunc' to vim.lua_omnifunc #32491

Problem:
- Many other ftplugin have defined 'omnifunc', but the Lua one doesn't
  define one, even though there is `vim.lua_omnifunc()`
- Users may want "stupid" completion to fix Lua config with
  `nvim --clean` in case they breaks it

Solution:
Set 'omnifunc' to 'v:lua.vim.lua_omnifunc' in ftplugin/lua.lua
