Introduce a logging method wrapper for importVerifyModule

[tomdol]

This is a proposal of a change of the underlying behavior of the ImporterEx::importVerifyModule method.

It's related to the comments in the NPU_Compiler/pull/20425 pull request where the switch to the current version of this method has been rejected.

The proposal changes the error handling of importVerifyModule from writing directly to std::cerr to throwing an exception instead. This way different users of this method can decide how they want to handle the error.

At the same time this PR contains a helper function which maintains the behavior in this repository - the verifier error, if occurs, will be logged to std::cerr. The code adaptation in this repository is also minimal with this approach.

The suggested change can be contained in the ImporterEx class too, the base throwing functionality can be kept in one method while another (new) method can catch the exception and log to cerr. This way the impact on the existing call sites of importVerifyModule can be reduced even further.
