Subject: [PATCH] [GHA] Cxx interoperability compatibility and integration
 tests check

# Motivation

Another reusable check is to make sure that all library products of a package are successfully building when consumed from a module that has Cxx interoperability enabled. Another check that's missing is running the integration tests.

# Modification

This PR adds two new checks to the reusable workflow. One to check for Cxx interoperability compatibility and another one to run the integration tests. I also fixed a misalgined name for the nightly benchmarks.

# Result

This should be one of the last reusable workflow checks.
