Add new error condition for DeviceBuilder

If an application uses add_required_extension_features but also adds
a VkPhysicalDeviceFeatures2 to the pNext chain of VkDeviceCreateInfo,
this will now result in an error. The reason is that Vk-Bootstrap is
perfectly capable of adding VkPhysicalDeviceFeatures to the pNext
chain itself but only if the user didn't already add their own.
