Refactor updates for Varbase Email by moving hook updates to include/updates with load Include based on major branches

Problem/Motivation

Having old hook updates back from ~9.0.0, and ~10.0.0 in the same location in the varbase_email.install file.

Which brings number of conflicting issues for order of hooks when committing, and updating a miner or batch fix release.
Having issues when updating an old version in the old branch, then the latest branch has to shift and have the old hook updates before.
To prevent issues when upgrading to a major release.

Proposed resolution

Keep all hook updates, but archive them.
not to remove any of them

• Add the include/updates folder into the module.
• Move hook updates to include/updates/v9.inc, include/updates/v10.inc
• Add the include/updates/all.inc file and add the following:
  

          \Drupal::moduleHandler()->loadInclude('varbase_email', 'inc', 'include/updates/v9');
          \Drupal::moduleHandler()->loadInclude('varbase_email', 'inc', 'include/updates/v10');
      

• Add the following to the varbase_email.install file
  \Drupal::moduleHandler()->loadInclude('varbase_email', 'inc', 'include/updates/all');

Add more inc includes for more update files when needed.
