Possible false positive 08608

If a pipeline is bound to the pipeline bind point used by this command, there must not have been any calls to dynamic state setting commands for any state specified statically in the VkPipeline object bound to the pipeline bind point used by this command, since that pipeline was bound

If a pipeline doesn't use tessellation, is it valid to call vkCmdSetPatchControlPointsEXT() after the pipeline is bound?

TEST_F(PositivePipeline, SetUnrelatedDynamicStateAfterBind) {
    TEST_DESCRIPTION("Set vkCmdSetPatchControlPointsEXT after pipeline is bound that does not use tessellation");

    AddRequiredExtensions(VK_EXT_EXTENDED_DYNAMIC_STATE_2_EXTENSION_NAME);
    AddRequiredFeature(vkt::Feature::extendedDynamicState2PatchControlPoints);
    RETURN_IF_SKIP(Init());
    InitRenderTarget();

    CreatePipelineHelper pipe(*this);
    pipe.CreateGraphicsPipeline();

    m_command_buffer.Begin();
    m_command_buffer.BeginRenderPass(m_renderPassBeginInfo);
    vk::CmdBindPipeline(m_command_buffer.handle(), VK_PIPELINE_BIND_POINT_GRAPHICS, pipe.Handle());
    vk::CmdSetPatchControlPointsEXT(m_command_buffer.handle(), 4u);
    vk::CmdDraw(m_command_buffer.handle(), 3u, 1u, 0u, 0u);
    m_command_buffer.EndRenderPass();
    m_command_buffer.End();
}

this is related to #7858 (https://gitlab.khronos.org/vulkan/vulkan/-/issues/3868)

basically we need to get a spec clarification (now that we seem to have so much CTS coverage) to show that dynamic state can be "ignored" if not used for certain parts of the pipeline
