Re: [PATCH v4 0/1] MR523: vkd3d: Use mutable descriptors if available.

Giovanni Mascellani (@giomasce) commented about libs/vkd3d/device.c:

Enabling the extension is not enough. You also have to check and enable `VkPhysicalDeviceMutableDescriptorTypeFeaturesEXT::mutableDescriptorType`. More in general, the Vulkan validation layer seems to have a few comments about your implementation (eventually we should probably consider enabling the validation layers in the CI).
