Use VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT when DI is enabled

**Description**

Intel doesn't support high counts of bindings in one bind group (250 being the limit) without using UPDATE_AFTER_BIND_BIT on the descriptors. It's my impression that there are no extra requirements for it, so we should enable it on the descriptors, sets, and pools in the vulkan backend when DI is enabled. 

I need to double-check things before we implement it.
