vk_device: Stop initialization when device is not suitable 

VKDevice::IsSuitable was not being called. To address this issue, check
suitability before initialization and throw an exception if it fails.

By doing this, we can deduplicate some code on queue searches.
Previosuly we would first search if a present and graphics queue
existed, then on initialization we would search again to find the index.
