chore: use cargo-wdk to build & package samples on the CI pipeline

[krishnakumar4a4]

This PR aims to use cargo-wdk to build and package the driver samples in the repository on the CI pipeline.
Changes:

1. Added continue-on-error = true to the build job. Without this change, one job failure cancels all the other jobs triggered in the matrix. Since other jobs are being cancelled, we won't be able to know the possible failures/successes of those jobs while most of them have executed 70% of the steps at any given time.
2. Added continue-on-error = true to the "Build and Package Sample Drivers in the workspace with cargo-wdk" step as cargo-wdk fails for known reasons due to a mix of sample and non-sample drivers in the workspace. cargo-wdk currently can work with one kind of setup, either all are sample drivers or none.
3. Note: The cargo-wdk used in the pipeline is taken from https://github.com/svasista-ms/windows-drivers-rs and from integrate-cargo-wdk branch as this PR is still not merged. This pipeline needs to get updated with cargo-wdk from https://github.com/microsoft/windows-drivers-repo once it is merged.

About cargo-wdk

cargo-wdk is a Command-Line Interface (CLI) utility that can be used to create and build Windows driver projects that depend on the WDK and windows-drivers-rs platform. It aims to streamline management of Rust drivers. It provides an easy and a consistent way to get started with Rust driver projects and build them using simple commands. It eliminates a lengthy setup process and also the need to maintain additional files/tools (Makefiles for cargo-make) to build/package the drivers.

Note: cargo-wdk is yet to be merged into windows-drivers-rs repo and it under review here
