In the case of buffer to image stores, we work around the limitation
for linear images by loading D/S data into a the color tile buffer
using a compatible format, however, this only works for formats with
a single aspect, for combined depth/stencil formats, since the copies
are specified to only copy a single aspect, we need to be able to
preserve the contents of the other aspect in the destination image,
and for that we still use the depth/stencil buffer, so we are affected
by the restriction.
Fixes some VK_KHR_maintenance5 CTS tests that hit this scenario,
such as some tests in:
dEQP-VK.api.copy_and_blit.core.image_to_image.all_formats.depth_stencil.2d_to_1d.*
In the case of image to image copies, we don't have any workarounds for
linear depth/stencil so we always want to skip the TLB path. I have not
seen any tests hit this scenario.
