Blocked non-list operations on adapters

[anmenaga]

PR Summary

Fix #516

Currently when non-list operations are executed on an adapter the error message is misleading;
This PR adds a check early in the call chain and prints a clear error message.

For example:

PS C:\DSCv3> dsc.exe resource export -r "Microsoft.DSC/PowerShell"   
2024-08-21T21:04:41.326009Z ERROR Can not perform this operation on the adapter Microsoft.DSC/PowerShell itself

Seems like the check should be in the lib instead of the exe, perhaps here? https://github.com/PowerShell/DSC/blob/main/dsc_lib/src/dscresources/dscresource.rs#L190

I've tried this, but realized that because the way we call adapted resources (we substitute adapted resource with adapter before calling lib's get/set/etc...) a way to differentiate between a call on an adapted resource vs call on an adapter within the lib is not trivial and I think it's not worth it.
