Details:

Add Vulkan glad2 support!

When I use glad2 for Vulkan I get errors that the imgui library cannot find Vulkan functions. I created this hotfix to resolve this issue. Error example: imgui/backends/imgui_impl_vulkan.cpp:1582:(.text+0x4936): undefined reference to vkDestroySemaphore

In imgui_impl_vulkan.h we should change 56-66 lines to:

#ifdef IMGUI_IMPL_VULKAN_USE_VOLK
#include <volk.h>
#else
#ifdef IMGUI_IMPL_VULKAN_USE_GLAD
#include <glad/vulkan.h>
#else
#include <vulkan/vulkan.h>
#endif
#endif

And also fix 96 line from VkPipelineRenderingCreateInfoKHR to VkPipelineRenderingCreateInfo

Thanks for attention!

(FFS, another Vulkan loader. Vulkan is going the route of OpenGL :( )
