Change argument input prompt from launch.json loading module to run asynchronously using vim.ui.input()

[MahboobMMonza]

Problem Statement

Currently, the load_launchjs functionality resolves "promptString" evaluations with vim.fn.input to ask for the user input, which is a blocking statement. Instead, vim.ui.input could be used instead to create a coroutine that can asynchronously ask for user input so that other processes can continue, as well as provide an easier extensibility point for UI configurations.

Possible Solutions

Implement the prompts with vim.ui.input and coroutines instead. Example (from my override for prompting inputs in nvim-jdtls):

local function get_inp()
  return coroutine.create(function(dap_run_co)
    vim.ui.input({ prompt = 'Args: ' }, function(argstr)
      coroutine.resume(dap_run_co, argstr)
    end)
  end)
end
