anv: descriptorBindingUniformBufferUpdateAfterBind feature is not supported
Unlike the windows driver, anv does not support the descriptorBindingUniformBufferUpdateAfterBind from the VK_EXT_descriptor_indexing extension. This feature would allow more optimal draw batching for the RPCS3 emulator, where we cannot reuse descriptors as normal applications can and have to do everything dynamically. Given the healthy performance gains observed with other vendors when using this extension, I am curious if it is a hardware limitation that keeps this from working on anv.
