Disables Vulkan devices sorting by default

Browse Source 
Currently we always choose the best device. But it's not always
desirable. A more safe approach is to use the default device (with
index 0). The only downside of that is if a user didn't adjust
settings then the game might run on an integrated GPU instead of a
discrete one. In the future it'll be solved by selecting GPU in
options: #8529

Fixes #8455
