Ghazi-raad 5a0679b862 Fix null pointer dereference in G-API stateful kernels ...

Fixes #28095

Problem:
- Stateful kernels dereference null state pointer on line 446 in gcpukernel.hpp
- jinboson confirmed state_ptr is null on x86 Ubuntu (7 hours ago)
- Causes crash with std::shared_ptr assertion on LoongArch64 and strict platforms

Solution (addressing Copilot review feedback from PR #28096):
1. Added null pointer check using CV_Error instead of CV_Assert:
   - CV_Assert with && 'message' doesn't display the message correctly
   - CV_Error properly reports cv::Error::StsNullPtr with clear message

2. Fixed test kernels to properly initialize state using std::make_shared:
   - GOCVStInvalidResize: Initialize state in setup()
   - GOCVCountStateSetups: Initialize state before incrementing counter
   - Used std::make_shared<int>() for modern C++ best practice

Impact:
- Prevents crashes on platforms with strict null pointer checking
- Provides actionable error message for developers
- Fixes StatefulKernel.StateInitOnceInRegularMode and InvalidReallocatingKernel tests
