Description

Currently Amber picks the first VkPhysicalDevice that meets its feature and extension requirements. Setting `VK_ICD_FILENAMES` is sufficient in most cases but not when trying to choose between two devices using the same ICD.

My idea was to add two new command line options:

* List physical Vulkan devices with IDs and exit
* Specify Vulkan device ID to run with
