...when the platform does not support Vulkan. The version is left
at the default 0 then, so checking for >= 1.0 is wrong.
This allows the test to pass with the offscreen platform plugin.

This also needs improvements to qvkgen. What we get with this patch
are the Vulkan 1.1 and 1.2 core API's additional 11 instance-level
and 30 device-level commands present in QVulkanFunctions and
QVulkanDeviceFunctions.
All of these are attempted to be resolved upon construction. When the
implementation does not return a valid function pointer for some of them
(e.g. because it is a Vulkan 1.0 instance or physical device), calling
the corresponding wrapper functions will lead to unspecified behavior.
This is in line with how QOpenGLExtraFunctions works. The simple
autotest added to exercise some Vulkan 1.1 APIs demonstrates this in
action.
The member functions in the generated qvulkan(device)functions header
and source files are ifdefed by VK_VERSION_1_{0,1,2}. This is essential
because otherwise a Qt build made on a system with Vulkan 1.2
headers would cause compilation breaks in application build environments
with Vulkan 1.0/1.1 headers when including qvulkanfunctions.h (due to
missing the 1.1/1.2 types and constants, some of which are used in the
function prototypes). In practice this should be alright - the only
caveat to keep in mind is that the Qt builds meant to be distributed
to a wide variety of systems need to be made with a sufficiently new
version of the Vulkan headers installed, just to ensure that the
1.1 and 1.2 wrapper functions are compiled into the Qt libraries.

...as described in the Vulkan >= 1.1 spec. One can now call
supportedApiVersion() (before create(), similarly to the other
supported* functions) to determine the available Vulkan

The Vulkan spec changed the behavior for VkApplicationInfo::apiVersion
in 1.1, conveniently breaking compatibility with all existing 1.0 logic.
We can no longer assume that the 1.0 behavior, which was failing instance
creation with VK_ERROR_INCOMPATIBLE_DRIVER for an unsupported version,
is always in place. So do not rely on this in the test, and add a
reminder in QVulkanInstance docs as well.

The qWaitFor functions themselves can not trigger a test failure, as that
will not result in the test function exiting early, so every single call
to qWaitFor needs to be wrapped in a QVERIFY.

A convenience subclass of QWindow that provides a Vulkan-capable
window with a double-buffered FIFO swapchain.
While advanced use cases are better served by a custom QWindow
subclass, many applications can benefit from having a convenient
helper that makes getting started easier.
Add also three examples of increasing complexity, and a variant that
shows embeddeding into widgets via QWindowContainer.

Linux aarch64 with Tegra X1 (Jetson TX1, L4T).
Introduce QPA-based Vulkan library loader, core function resolver, and
instance creation support. In addition to creating a new VkInstance,
adopting an existing one from an external engine is supported as well.
The WSI specifics are hidden in the platform plugins. Vulkan-capable
windows use the new surface type VulkanSurface and are associated with
a QVulkanInstance.
On Windows VULKAN_SDK is picked up automatically so finding vulkan.h
needs no additional manual steps once the LunarG SDK is installed.
