A compute shader addressing an image with MIMG DIM 2D over a T# of type 2D
array was refused ("guest storage texture dimension disagrees with the
shader's declared image shape"). Such an access carries no slice
coordinate, so the hardware reads and writes slice 0 of the resource view,
which is the BASE_ARRAY layer of the surface.
The storage element is now bound through a 2D view of that layer of the
surface's shared storage image (StorageTexture::FirstLayerView, created on
demand per mip and released with the image). Every other shape/dimension
mismatch still throws, and both mismatch messages now name the shape and
the dimension.
The recorder test device sets formatProperties, which storage images need
to pick their Vulkan format.
