Remove redundant Vulkan API version checks

[sfricke-samsung]

As discussed in #1541

The code

for (auto promoted_ext : V_1_1_promoted_device_apis) {
    info = get_info(promoted_ext);
    if (info.state) this->*(info.state) = kEnabledByApiLevel;
}

Adds all core extensions when a version is detected.

For example there is no need to do

if ((api_version >= VK_API_VERSION_1_1) || (device_extensions.vk_khr_maintenance1)) {
   // VUID-x
}

Since the 1.1 check is redundant here.

This issue is to track the removal of other redundant checks
