It is not required to check if the model is already loaded or not.
Python automatically does this.

It's not a good practice to have a module as a class variable. When you remove the dependency of checking if the module in already imported, this is not required.

This PR updates QEff to support QPC generation on systems without the Platform SDK by refactoring the module loading behavior. Users can now compile models and generate QPCs using QEff with only the Apps SDK installed.
Background: Previously, both Apps SDK and Platform SDK were required to compile and generate QPCs using QEff. The goal is to allow QPC generation with only the Apps SDK installed for systems without Ultra cards.
Changes:
Refactored init.py and generation/cloud_infer.py to use lazy loading via importlib for qaicrt and aicapi.
This ensures that Platform SDK-dependent modules are only loaded when explicitly needed, avoiding import errors during initialization and QPC generation.
