Switch from Drupal module load Include to native PHP include once for Varbase API to include all helpers and updates

Problem/Motivation

Follow up issue after
#3400109: Refactor updates for Varbase API by moving hook updates to include/updates with load Include based on major branches

The \Drupal::moduleHandler()->loadInclude function operates slowly and necessitates the installation of the associated module to ensure proper formatting and logical functioning.

Proposed resolution

Change to

// Include all helpers and updates.
include_once __DIR__ . '/includes/helpers.inc';
include_once __DIR__ . '/includes/updates.inc';
