Fix 'auto' GPU identification and display

Browse source 
* Refactors the previous code segment
* Fixes 'auto' GPU identification and display in DDNet Graphics tab of
  the settings. The 'auto' GPU is the best one encountered in the VK
  physical device enumeration array until we encounter one that is
  at least "integrated" when accessing them in increasing order
* Selects the first GPU that matches a name when using one by user
  specified name
