Revert "Sort PhysicalDevices to match ICD's ordering"

[charles-lunarg]

Reverts #1744

The change breaks angle tests which fail to find the correct physical device. An example failure error is:

[ RUN      ] TraceTest.supertuxkart
WARN: vulkan_icd.cpp:388 (ChoosePhysicalDevice): Preferred device ICD not found. Using default physicalDevice instead.
GL_RENDERER: ANGLE (Mesa, Vulkan 1.3.255 (llvmpipe (LLVM 15.0.7 256 bits) (0x00000000)), llvmpipe-0.0.1)
