[Mesa-dev] [PATCH v2 08/13] anv/blorp: Remove 3D subresource transition workaround

[Nanley Chery]

For 3D image subresources undergoing a layout transition via
PipelineBarrier, we increase the number of fast-cleared layers to match
the intended behaviour of KHR_maintenance1. When such subresources
undergo layout transitions between subpasses, we don't do this to avoid
failing incorrect CTS tests. Instead, unify the behaviour in both
scenarios, and wait for the CTS tests to catch up. See CL 1111 for the
test fix and Vulkan issue #849 for more information.

On SKL+, this causes 3 test failures under:
dEQP-VK.pipeline.render_to_image.3d.*

v2: Add a reference to the Vulkan issue (Iago Toral).
