[BUILD] Use Cancel workflow action to cancel outdated PR build jobs

### Motivation

Currently a single user can cause the Github Actions / Workflows based CI to get overloaded when commits are pushed to a PR branch frequently, one by one. To mitigate this issue, cancel any previous Github Actions runs that are not completed for a given workflow,  for a particular branch / PR. This can be achieved by using the https://github.com/marketplace/actions/cancel-workflow-action .
[There are multiple cancel actions available](https://github.community/t/github-actions-cancel-redundant-builds-not-solved/16025/22). This particular one was picked based on its popularity.

### Modifications

Append each workflow with the cancel workflow action step.

A similar change was made in Pulsar CI in PR https://github.com/apache/pulsar/pull/8393
