anv/image: Rework YCbCr image aspects

The Vulkan 1.2.184 spec says:

    "When creating a VkImageView, if sampler Y′CBCR conversion is
    enabled in the sampler, the aspectMask of a subresourceRange used by
    the VkImageView must be VK_IMAGE_ASPECT_COLOR_BIT.

    When creating a VkImageView, if sampler Y′CBCR conversion is not
    enabled in the sampler and the image format is multi-planar, the
    image must have been created with
    VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT, and the aspectMask of the
    VkImageView’s subresourceRange must be VK_IMAGE_ASPECT_PLANE_0_BIT,
    VK_IMAGE_ASPECT_PLANE_1_BIT or VK_IMAGE_ASPECT_PLANE_2_BIT."

Previously, for YCbCr images, we were flipping this around.  For single-
plane views where VK_IMAGE_ASPECT_PLANE_N_BIT would be passed in by the
app, we would store VK_IMAGE_ASPECT_COLOR_BIT.  For multi-plane views
where the client says VK_IMAGE_ASPECT_COLOR_BIT, we would store a all of
the planes.  (There was also an extra bit of remapping that would
compact the planes in the non-existent case of a format with a non-
contiguous set of planes.)  The idea behind this was that for things
like rendering or single-plane sampling, storage, or compute, we want it
to look as much like a single-plane image as possible but we wanted the
multi-plane case to be the awkward one.

This commit changes it around so that iview->aspects is always exactly
the subset of image->vk.aspects represented by the view.  This is
identical to how aspects work for depth/stencil so it gains us some
consistency.

This commit also changes anv_image_view::aspect_mask to aspects to force
a full audit of the field.  As can be seen, there are only a few uses of
this field and they're all mostly fine:

 - A bunch of them are used to check for depth/stencil.  That hasn't
   changed.

 - Most of the checks for color already used ANY_COLOR_BIT, only one
   needed fixing.

 - There's a check that both src/depth are color for MSAA resolves.
   However, we don't support MSAA on YCbCr so there's no point in
   checking for ANY_COLOR_BIT.

There is a hidden usage of planes in anv_descriptor_set_write_image_view
that's not as obvious.  However, this function simply looks at
anv_image_view::n_planes and blindly fills out the descriptor
accordingly.  As long as image views with a single plane continue to
claim n_planes == 1, this will be fine.
