Examples: Vulkan: Fixed an extra validation (tested on Windows with VulkanSDK 1.0.46.0) (#1042)

Examples: Vulkan: Various very minor stylistic fixes, fixing typos in comments, etc. (#1042 #1043)

Image presentation now depends on the completeness of command buffer submission through semaphores. ...

To maintain maximum frame rate we render to the last acquired swapchain image but present the last but one drawn image. This behavior is optional through conditional compilation macros.

Removed redundant VkResult plugged into VkPresentInfoKHR pResults attribute. This is only meaningful when we present directly to multiple swapchains. In that case we can an VkResult per swapchain.

Removed redundant barrier. ...

The transition of the swapchain image(s) can happen implicitly in the renderpass. This approach has been stated to be more efficient than using an explicit barrier.
See "Vulkan Programming Guide", Chapter 7: "Graphics Pipelines", section "Renderpasses".

Fixed all issues found by vulkan debug report. Reasons for the major design changes are commented.

Examples: Vulkan: Disable IMGUI_VULKAN_DEBUG_REPORT by default. Update .bat files for newer VulkanSDK.

Vulkan backend: optionally enabling vulkan validation layers and debug report callback ...

Additional layer, extension and the callback itself are used/created when IMGUI_VULKAN_DEBUG_REPORT is defined. The callback reports seven (potential!) errors which will be fixed with another pull request.

AFAIK there's no such enum as `GL_BLEND_SRC` or `GL_BLEND_DST` in OpenGL3 and OpenGL4.

Maybe they're left over from previous versions? They don't even seem to exist in OpenGL 2.1. In fact checking they were deprecated in OpenGL 1.5 (they exist in 1.3)
