Prefer drupal_debug() to the now-ambiguous dd()

Problem/Motivation

The views_debug() function calls dd(), expecting to get the devel module function.

Devel defines dd() as a shorthand for calling drupal_debug().

Drush uses the symfony/var-dumper library which in recent versions has introduced a dd() function in the global namespace (which seems somewhat ironic for an OOP-obsessed framework, but there we are).

Both symfony/var-dumper and devel have both 'addressed' this issue in the same way:

if (!function_exists('dd')) {
  function dd(...) {
    ...
  }
}

This prevents PHP parse errors but, depending on the request, Views can't know which function it's going to end up calling.

Steps to reproduce

Refer to:

In: web/sites/all/modules/development/devel/devel.module
1 [dd] function dd($data, $label = NULL) {

In: .composer/vendor/symfony/var-dumper/Resources/functions/dump.php
2 [dd] function dd(...$vars)

Proposed resolution

Use drupal_debug() directly.

A shorthand is useful in a REPL, but committed code should prefer the 'real' name -- even without the clash there's a micro-efficiency in not calling a wrapper function; but with the clash it's important to use the dependable name.
