Remove vertex stage variants from dEQP-VK.protected_memory.interaction.ycbcr.*

Remove vertex stage variants from dEQP-VK.protected_memory.interaction.ycbcr.*

"Except for framebuffer-space pipeline stages, compute shader stage, and
transfer stage, any read from or write to protected memory during protected
queue operations results in undefined behavior"

The existing dEQP-VK.protected_memory.interaction.ycbcr.* group include
tests that sample the protected texture from inside the vertex shader. This
commit removes these tests.

Tests affected:
dEQP-VK.protected_memory.interaction.ycbcr.*

Components: Vulkan

VK-GL-CTS issue: 1031
