Fix early fragment tests validation errors

There are several issues in the tests which were found by running them
with turnip driver with sysmem mode and the validation layers enabled:

- There was a sync issue. The culprit was
srcAccessMask=VK_ACCESS_SHADER_WRITE_BIT in one image memory barrier
since per spec for the store op "For attachments with a depth/stencil
format, this uses the access type
VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT.". So the correct
synchronization should have src access mask
VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT.

- In the same image memory buffer, the image layout was wrong when
testing stencil images.

- There were validation errors related to wrong image layout settings.

VK-GL-CTS issue: 3083
Components: Vulkan
