feat(lsp): root_markers can control priority #33485

Browse Source 
Problem:
root_markers cannot specify "equal priority filenames.

Solution:
Support nesting:

    {
      ...
      root_markers = { { ".stylua.toml", ".luarc.json" }, { ".git "} }
      ...
    }

--- The list order decides the priority. To indicate "equal priority", specify names in a nested list (`{ { 'a', 'b' }, ... }`)
--- Each entry in this list is a set of one or more markers. For each set, Nvim
--- will search upwards for each marker contained in the set. If a marker is
--- found, the directory which contains that marker is used as the root
--- directory. If no markers from the set are found, the process is repeated
--- with the next set in the list.
---
--- Example:
---
--- ```lua
--- root_markers = { 'stylua.toml', '.git' }
--- ```
---
--- Find the first parent directory containing the file `stylua.toml`. If not
--- found, find the first parent directory containing the file or directory
--- `.git`.
---
--- Example:
---
--- ```lua
--- root_markers = { { 'stylua.toml', '.luarc.json' }, '.git' }
--- ```
---
--- Find the first parent directory containing EITHER `stylua.toml` or
--- `.luarc.json`. If not found, find the first parent directory containing the
