Add required support check for IsHelperInvocationEXT test

IsHelperInvocationEXT test requires the GroupNonUniformQuad capability,
but it did not check for VK_SUBGROUP_FEATURE_QUAD_BIT in
VkPhysicalDeviceSubgroupProperties::supportedOperations. This commit
adds the support check for needed feature.

Components: Vulkan
