ci: add concurrency control to workflows

[svasista-ms]

Closes #38

Cancels in-progress workflows/jobs for the build workflow when new events are triggered on the same branch

Summary of changes:

• Added concurrency section to the build.yaml workflow
• Added cancel-in-progress: true to cancel any currently running job or workflow in the same concurrency group.

The build pipeline is failing due to the following error. Once it is fixed, I think this one is good to be merged.

stderr:
error: unnecessary parentheses around closure body
  --> rust-env-update.rs:21:25

21 |         .map(|(key, _)| (key)),

   = help: to override `-D warnings` add `#[allow(unused_parens)]`
help: remove these parentheses

21 -         .map(|(key, _)| (key)),
21 +         .map(|(key, _)| key),

I’ve noticed that this error originates from the wdk-build dependency. Although the fix has been merged and is available on the main branch, a release needs to be created before we can use it here.

Yes @krishnakumar4a4, this PR can't be merged until a new version of wdk-build is published.
