Settings file with device configuration doesn't apply to vkEnumeratePhysicalDeviceGroups

[richard-lunarg]

Issue was moved from Vulkan-ValidationLayers to Vulkan-Loader

The settings file allows specifying which VkPhysicalDevice's should be visible to applications. This logic applies to the ouput of vkEnumeratePhysicalDevices. It currently doesn't apply to vkEnumeratePhysicalDeviceGroups which is a bug, and causes the validation layer to crash if an app tries to create a VkDevice using a VkPhysicalDevice queried by vkEnumeratePhysicalDeviceGroups.

Original issue

Environment:

• OS: MacOS
• GPU and driver version: MoltenVK or KosmicKrisp
• SDK or header version if building from repo: 1.4.350.0
• Options enabled (synchronization, best practices, etc.):
  Default Presets from Vulkan Configurator

Vulkan Configurator allows you to force a single driver to be used on the "Vulkan Drivers" tab. If you select "Force a single Vulkan physical device", and have validation enabled with the default presets, vulkaninfo will segfault. It does not matter if you choose MoltenVK or KosmicKrisp. It crashes right after starting the device groups as shown below. This is likely a conflict with how the newer loaders allow device filtering, which is being exposed by Vulkan Configurator here.

Device Groups:

Group 0:
Properties:
physicalDevices: count = 1
Apple M4 Max (ID: 0)
subsetAllocation = 0

zsh: segmentation fault vulkaninfo

This can be reproduced on Windows as well and Linux. Any system with multiple drivers seems to have the same bug.
