Merge pull request #25122 from unnonouno:pqueue
Use std::priority_queue in inpaint function for performance improvement #25122

In `cv::inpaint` implementation, it uses a priority queue with O(n) time linear search. For large images it is very slow.
I replaced it with C++'s standard library `std::priority_queue`, that uses O(log(n)) algorithm.
In my use case, it is x10 faster than the original.
