System.DirectoryServices libraries should conform to interop guidelines

[mthalman]

The following list of directories/files do not conform to the interop guidelines:

• https://github.com/dotnet/runtime/tree/main/src/libraries/System.DirectoryServices/src/Interop
• https://github.com/dotnet/runtime/tree/main/src/libraries/System.DirectoryServices.Protocols/src/System/DirectoryServices/Protocols/Interop
• https://github.com/dotnet/runtime/blob/main/src/libraries/System.DirectoryServices.AccountManagement/src/System/DirectoryServices/AccountManagement/interopt.cs

Specifically, the file organization section states that all Interop.*.cs files should all be defined in the Common directory. Conforming to the guidelines and having a standardized way of defining native interop supports the work for being able to track and detect platform dependencies.

@mthalman was this covered by your recent PR #51325 ?

[mthalman]

No, that PR was only meant to move the needle closer to conforming with the guidelines, but not all the way. My original statement is still relevant and should be addressed:

Specifically, the file organization section states that all Interop.*.cs files should all be defined in the Common directory.
