Arm runners for samples repo CI pipeline

[krishnakumar4a4]

Arm runner support has been merged into https://github.com/microsoft/windows-drivers-rs as part of microsoft/windows-drivers-rs#364.

This issue is about adding Arm runner support to the samples repository as well.

Note: This depends on the changes from microsoft/windows-drivers-rs#214, which will only be available after a new wdk-build release is published.
