Revert "Add a force_replace_host flag to win_domain_membership (#53542)" (#55056)

This reverts commit 85d836171b.

As discussed in WWG IRC meeting, we don't want Get-ADObject to be a dependency of win_domain_membership, and we need to be able to authenticate to the DC in some configs. We can revisit this change a different way for 2.9.

 * The ``win_dsc`` module will now validate the input options for a DSC resource. In previous versions invalid options
   would be ignored but are now not.
 
-* The ``win_domain_membership`` module will no longer automatically join a host in a domain that already has an account
-  with the same name. Set ``allow_existing_computer_account=yes`` to override this check and go back to the original
-  behaviour.
