Windows: Add "special" parameter types to docs (#42853)

* Windows: Add special parameter types

Adding explicit parameter types now exposes this information in the
module documentation, and proves really helpful.

We only do this for non-string types as strings, mostly because strings
are implicit.

PS We also make copyright statements consistent and use #Requires for
explicit library imports

* Type "string" must be type "str"

* A few more Copyright corrections

* More fixes

* Don't add file encoding to Powershell files

* Don't add missing interfacetypes parameter

Otherwise CI demands an incorrect version_added

* Small fix
