Code: Use uint32_t for WIDTH and HEIGHT to prevent narrowing conversion

A warning would otherwise be raised from "Swap chain" onward when using
GCC 9.3.0:
```
g++ -std=c++17 -o HelloTriangle main.cpp `pkg-config --static --libs glfw3` -lvulkan
main.cpp: In member function ‘VkExtent2D HelloTriangleApplication::chooseSwapExtent(const VkSurfaceCapabilitiesKHR&)’:
