Fix feature checks in rasterization order attachment tests

Fix feature checks in rasterization order attachment tests

This commit fixes the following issues:

* Do not filter the extension by default.
* Do not require Vulkan 1.2 in the tests.
* Chain the features struct in the right place when requesting it.
* Choose a supported depth/stencil format at runtime.
* Do not require the extension in explicit synchronization variants.
* Add missing VK_DEPENDENCY_BY_REGION_BIT in some barriers.

Affected tests:
dEQP-VK.rasterization.rasterization_order_attachment_access.*

Components: Vulkan
VK-GL-CTS issue: 3528
