layers: multiplane image allow color aspect bit

There is a case (memory barrier) where a multiplane image can have
the color aspect bit set, so the general aspect check should allow
it. In the common case where only VK_IMAGE_ASPECT_PLANE_n_BIT_KHR
bits are allowed, there are specific VUIDs in place to enforce.

This fixes an "unexpected error" result that recently appeared for
the CopyImageMultiplaneAspectBits test.
