vmware: test-refactoring

- In order to keep the integration with `ansible-test`, we prefer to avoid any
  interaction with the Ansible inventory file.
- split up the prepare_vmware_tests/defaults/main.yml in two
  configuration files: one for vcsim and one for a real environment
- remove all the access to hostvars
- directly interact with the ESXi to mount/umount the datastore
  https://github.com/ansible/ansible/pull/56516
- record the virtual machine folder in the environment configuration
- vmware_guest_move: Use https://github.com/ansible/ansible/pull/55237
