[cargo-wdk] Make cargo-wdk to work with a workspace containing both sample and non-sample drivers

[krishnakumar4a4]

Cargo wdk utility takes --sample as argument, which indicates that the workspace, emulated workspace, or standalone driver project contains all sample class drivers. Not passing --sample indicates that none of the driver projects are sample class drivers.

This issue supposed to remove this constraint and allow cargo wdk utility to work with both sample and non sample drivers in a workspace or an emulated workspace.

I'm already working on an INF file parser in rust that can help parse inf files to determine the class of the driver.
This helps remove the --sample argument entirely and also help to solve this issue to work with a workspace with a mix of sample and non-sample drivers.
