Adding module win_domain_computer (#35954)

* Adding module win_domain_computer

This module is a wrapper of powershell *-ADComputer commands.
The main use case is to add non-windows computers to Active Directory
through a bridge windows computer.

* Replace `Set-Attr`

* Fix case insensitive comparisons

* Add omitted parameters in cmdlets

* Enhance module documentation

* Simplify `state` as case insensitive.

* Simplify try catch

* Fix indentation

* Make message errors more descriptive.

* Specify type in boolean parameters

* Keep parameter ingestion together

* Delete superfluous resultobj

* Workaround failing Erroraction

* Add target info in error

* Cosmetic changes

* Fix up Fail-Json to use correct message param
