Fix all VMware examples to use delegate_to (#43426)

Some users have problems using the VMware modules because they use the
vCenter as target, and Ansible uses SSH to connect to the targets.

Eventually we need to update the VMware guide to explain how the modules
work, but the first fix is to update the examples.

(We should backport to v2.6 and v2.5 too)
