Extend copyImage tests with depth/stencil formats

Extend copyImage tests with depth/stencil formats

Add tests with all depth/stencil formats into image to image copies cases.
It was needed to fix the 'uploadImage' and 'readImage' functions, because
the copying combined dept/stencil data between buffers and images are not
supprted at the same time.

Update and fix the generation of expected image.

Update the mustpass lists.

Fix conflict after rebase.
