layers: GH650, Fix D/S image layout validation

When an imageView of a depth/stencil image is used as a depth/stencil
framebuffer attachment, the aspectMask is ignored and both depth and
stencil image subresources are used. Validation was throwing errors
as only the specified aspectMask transition was tracked.
