rhi: vulkan: Print vma statistics on out of device memory 

Following a vmaCreate* it makes sense to test for
VK_ERROR_OUT_OF_DEVICE_MEMORY and print the allocator statistics
in order to give an idea of the application's (video) memory
usage.

For instance when running on a Raspberry Pi 4, this helps to indicate
that the application is just too big for the device, and is more
informative then just a Failed to create image: -2 message.

Pick-to: 6.6 6.5
