create present queue and lots of code refactoring

- wait idle on present queue instead of graphics queue
- assume only one bit of VkDebugUtilsMessageSeverityFlagBitsEXT is set;
  it seems to be always the case
- rename every _create_info to _ci
- print less debug information, by reducing debug output to warning and
  up, and by removing printing of all of devices properties
- make as much blocks and lambdas as possible to contain every variable
  to a small scope
- use designator lists everywhere
- rename device to physical_device, and logical_device to device
