Enabling the PARTIALLY_BOUND_BINDING_ARRAY feature causes Vulkan Validation Error

[LPGhatguy]

Description
Requesting a device with the PARTIALLY_BOUND_BINDING_ARRAY feature and creating a bind group causes a Vulkan validation error:

VALIDATION [VUID-VkDescriptorSetLayoutBindingFlagsCreateInfo-descriptorBindingPartiallyBound-03013 (0x95331f1c)]
Validation Error: [ VUID-VkDescriptorSetLayoutBindingFlagsCreateInfo-descriptorBindingPartiallyBound-03013 ] Object 0: handle = 0x18d7125fc20, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x95331f1c | vkCreateDescriptorSetLayout(): pBindings[11] can't have VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT for VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE since descriptorBindingPartiallyBound is not enabled. The Vulkan spec states: If VkPhysicalDeviceDescriptorIndexingFeatures::descriptorBindingPartiallyBound is not enabled, all elements of pBindingFlags must not include VK_DESCRIPTOR_BINDING_PARTIALLY_BOUND_BIT (https://vulkan.lunarg.com/doc/view/1.3.216.0/windows/1.3-extensions/vkspec.html#VUID-VkDescriptorSetLayoutBindingFlagsCreateInfo-descriptorBindingPartiallyBound-03013)

Repro steps
Creating an adapter with Features::TEXTURE_BINDING_ARRAY | Features::PARTIALLY_BOUND_BINDING_ARRAY and then creating a BindGroup with a texture array appears to cause this validation error.

Expected vs observed behavior
wgpu should enable this Vulkan feature, but does not.
