The webgpu.h surface-based swapchains are implement on Metal which
required adding the present mode to NewSwapChainBase.
Additional automated tests are added which require getting the Instance
so a new getter is added to DawnTest. Additional some the state tracking
of swapchains is performed in the backend, so the
SwapChainValidationTests are turned into regular DawnTests so they can
check backends do the correct state tracking. To not lose coverage of
the Null backend, a NullBackend() DawnTestParam factory is added.
Finally swapchains cannot be entirely tested in an automated fashion, so
a new example is added called "ManualSwapChainTests" that allows
manually checking a number of properties. Documentation of the controls
and a manual test plan is in a comment at the top of the example's
source.

Certain Vulkan ICDs (Intel ones notably) will compile SPIR-V
shaders with an liberal, compiler-selected, subgroup size (i.e.
either 8, 16 or 32). For more context, see [1].
This can be a problem for compute, when one shader stores data
in device memory using a subgroup-size dependent layout, to be
consumed by a another shader. Problems arise when the compiler
decides to compile both shaders with different subgroup sizes.
To work-around this, the VK_EXT_subgroup_size_control device
extension was introduced recently: it allows the device to
report the min/max subgroup sizes it provides, and allows
the Vulkan program to control the subgroup size precisely
if it wants to.
This patch adds support to the Vulkan backend to report and
enable the extension if it is available. Note that:
- The corresponding VkStructureType enum values and
struct types are not rolled to the third-party Vulkan
headers used by Dawn yet, so vulkan_platform.h has been
modified to define them if necessary. This can be
removed in the future when the Vulkan-Headers are
updated in a different patch.
- This modifies VulkanDeviceInfo::GatherDeviceInfo() to
use VkGetPhysicalDevice{Properties2,Features2} if the
VK_KHR_get_device_properties2 instance extension is
available. Otherwise, the Vulkan 1.0 APIs
VkGetPhysicalDevice{Properties,Features} are used instead
(and it is assumed that no subgroup size control is
possible).
- This changes the definition of VulkanDeviceKnobs to
make room for the required pNext-linked chains of
extensions.
- A helper class, PNextChainBuilder is also provided in
UtilsVulkan.h to make it easy to build pNext-linked
extension struct chains at runtime, as required when
probing device propertires/features, or when
creating a new VkDevice handle.
Apart from that, there is no change in behaviour in this CL.
I.e. a later CL might force a specific subgroup size for
consistency, or introduce a new API to let Dawn clients
select a fixed subgroup size.
