v3dv: don't resolve by averaging samples on depth/stencil resolves

For these we always want to use sample_0, averaging is reserved for
color formats. We were already doing this correctly for depth/stencil
resolved in render passes, but not for those happening through
vkCmdResolveImage.

Fixes some of the issues we have with CTS 1.3.4 in:
dEQP-VK.pipeline.monolithic.multisample.misc.*
