feat(lsp): allow passing custom list handler to LSP functions that return lists (#19213)

Currently LSP allows only using loclist or quickfix list window. I
normally prefer to review all quickfix items without opening quickfix
window. This fix allows passing `on_list` option which allows full
control what to do with list.

Here is example how to use it with quick fix list:

```lua
local function on_list(options)
  vim.fn.setqflist({}, ' ', options)
  vim.api.nvim_command('cfirst')
end

local bufopts = { noremap=true, silent=true, buffer=bufnr }
vim.keymap.set('n', '<leader>ad', function() vim.lsp.buf.declaration{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>d', function() vim.lsp.buf.definition{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>ai', function() vim.lsp.buf.implementation{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>at', function() vim.lsp.buf.type_definition{on_list=on_list} end, bufopts)
vim.keymap.set('n', '<leader>af', function() vim.lsp.buf.references(nil, {on_list=on_list}) end, bufopts)
```

If you prefer loclist do something like this:

```lua
local function on_list(options)
  vim.fn.setloclist(0, {}, ' ', options)
  vim.api.nvim_command('lopen')
end
```
