Improve handling of AnsibleModule arguments in validate-modules (#75332)

* Make sure AnsibleModule positional arguments are validated.

* Extract ANSIBLE_MODULE_CONSTURCTOR_ARGS with inspection.

* Remove no longer necessary return value.

* Fix PR #.

* argument_spec might not have been specified, as in community.general.xenserver_facts.

* Fix typo.
