Move hellovulkantexture example to manual test

Because it is the least documented one, and compared to the other
Vulkan examples it does not add anything new, it just dives deeper
into Vulkan.

-    \title Hello Vulkan Texture Vulkan Example
-    \brief Shows the basics of rendering with textures in a QVulkanWindow.
-
-    The \e{Hello Vulkan Texture Example} builds on \l hellovulkantriangle. Here
-    instead of drawing a single triangle, a triangle strip is drawn in order to
-    get a quad on the screen. This is then textured using a QImage loaded from
-    a .png image file.
