MDL-76052 webservice_xmlrpc: Remove it completely from core

Normal removal procedure:
  - Remove the plugin completely from core.
  - Document it in the webservices upgrade.txt file.
  - Add a core upgrade step to proceed to remove any configuration
    if the plugin has not been re-installed manually.

Plus:
  - Remove a few remaining uses in the hub/sites registration scripts,
    that were moved from xmlrpc to hand.made rest calls by MDL-31436
    (Moodle 3.4.1 and up) and never removed then.
  - Remove the php-xmlrpc extension as a recommendation in composer.
  - Remove "xmlrpc" from various comments, trivial cleanup.

Note:
  - While working on this MDL-76078 has been created about to
    fix a serious design problem detected (it does not affect
    functionality). That's out from this issue scope.
