Subject: lua: add vim.fn.{func} for direct access to vimL function

compared to vim.api.|nvim_call_function|, this fixes some typing issues
due to the indirect conversion via the API. float values are preserved
as such (fixes #9389) as well as empty dicts/arrays.

Ref https://github.com/norcalli/nvim.lua for the call syntax
