util/vulkan: Move Vulkan utilities to src/vulkan/util
We have Vulkan utilities in both src/util and src/vulkan/util. The latter seems a more appropriate place for Vulkan-specific things, so move them there. v2: Android build system changes (from Tapani Pälli) Signed-off-by: Alex Smith <asmith@feralinteractive.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Acked-by: Jason Ekstrand <jason@jlekstrand.net>
