Port implementation to VK_KHR_ray_tracing

[GPSnoopy]

• Updated Vulkan SDK to 1.2.35.
• Minimum Vulkan version is now 1.2.
• Using VK_KHR_ray_tracing Vulkan extension instead of VK_NV_ray_tracing.
• Using GL_EXT_ray_tracing GLSL extension instead of GL_NV_ray_tracing.
• Added debug util methods around vkSetDebugUtilsObjectNameEXT to keep track of object names.

Will merge once the VK_KHR_ray_tracing extension is not beta anymore.

Merging even though the extention is still prelimanary, as this is blocking further improvements (e.g. #12).
