Follow cl-gfx 02db471: Vulkan 1.4, its features, and surfaces destroyed at once
A device needs Vulkan 1.4, whose devices have every feature cl-gfx
enables on all: the optional features are :GEOMETRY-SHADERS,
:TESSELLATION-SHADERS, :FLOAT64, :MULTISAMPLE-STORAGE-TEXTURES and
:VERTEX-STORES, and cube arrays and anisotropic samplers need none. A
multisampled texture may be a :2D-ARRAY, and DESTROY-SURFACE waits for
the GPU and destroys the surface at once, between frames.
