venus: Enable VK_EXT_pipeline_creation_feedback
Implement natively by always returning invalid feedback. This is a legal
(but useless) implementation according to the spec.
In the future, I want to return the real feedback values from the host,
but that requires changes to the venus protocol. The protocol does not
know that the VkPipelineCreationFeedback structs in the
VkGraphicsPipelineCreateInfo pNext are output parameters. Before
VK_EXT_pipeline_creation_feedback, the pNext chain was input-only.
Tested with `dEQP-VK.pipeline.*.creation_feedback.*`.
The tests in vulkan-cts-1.3.3.0 are buggy. I submitted a fix to dEQP
upstream; see below.
