gpu_rb_storage makes the image with the samples asked for; a pass takes its attachments' count and
every pipeline in it matches; a blit from a multisampled source resolves on the end of an empty
dynamic-rendering pass (colour averaged, depth from sample zero - vkCmdResolveImage cannot do depth).
gpu_msaa_max reads the device's colour-and-depth sample limits, and post_set_msaa clamps to it, so
the Anti-aliasing setting is live on Vulkan. The pipeline cache's pass key no longer packs samples
into three bits.
