TravisCI - Build on Multiple CPU Architectures

[RishabhJain2018]

Issue:

Since we run the code on ARM64 and AMD64 architectures, the Travis build currently doesn't support both. We should include this in the build process to make sure that the new changes doesn't break the code.

Deliverables:

Modify the travis.yml and include both the architectures in the Travis build.

@RishabhJain2018 should I still work on this as we intend to shift? #4553

[RishabhJain2018]

Yes, we intend to shift but we will need the same in GIthub CI/CD.

Let's pause on this for now.
