As a side-effect this allows empty viewports which need special handling in Vulkan because it is not allowed to set width to 0 (but ok to set height to 0). Validation tests are updated to cover the new validation checks. Most of the viewport end2end tests are rewritten because they didn't pass the new validation. A new end2end test is added to test various kinds of empty viewports to cover the extra logic in the Vulkan backend.
