remove Vimscript wrapper nvim_lsp#setup()

Lua is easy to use from Vimscript, there is no reason to have multiple
ways to work with nvim-lsp.

- massively clarifies the "story" that users need to comprehend
- reduces surface area, maintenance, tests
- avoids constant "Vim or Lua" dance in the documentation
- simplifies discussions, tutorials, etc.
- avoids confusing situation for users that start with Vimscript but
  later need Lua-only features
