MacOS universal binary

[gmonceyron]

On behalf of @bhou:

Today, we are supporting two architectures in MacOS, X86 and ARM. Two versions of command-launcher are built from CI.

Sometimes, developer could accidentally download or copied the wrong architecture, this could lead to potential issues.

A solution for this is to create a universal binary. The lipo tool can help to create such binary. Example:
lipo -create -output universal_app x86_app arm_app

We can change the Github CI to generate such binary.
