Remove "Using present mode" verbose prints in Vulkan and Direct3D 12

These messages were printed every time the swapchain was recreated
(e.g. on viewport size change), which could easily end up spamming
the output.

The chosen present mode is already displayed when using the Print FPS
project setting or command line argument.
