534517ca63 Vulkan: Enable barrier validation using VK_EXT_validation_features.
This found a couple issues with readonly storage textures and buffers
and will prevent regression in the correctness of barriers in the Vulkan
backend.

2231fcda56 Vulkan: Add support for layer extensions.
This commit generalizes the way layers are handled to be more like
extensions, and adds support for gathering and enabling layer
extensions.

This is in preparation for using the VK_EXT_validation_features
extension to enable barrier validation.

Also adds logic to use the Fuchsia swapchain layer when it is available.
It seems to have been removed by mistake some time ago.

f091fb71f7 Vulkan: Use ityp::bitset for Instance/DeviceExtSet
ityp::bitset allows the creation of a bitset indexed by enums. Use this
instead of our custom wrapper around bitset that only supports .Set and
.Has.

f83df90fae Vulkan: use VK_EXT_debug_utils instead of deprecated extensions.
The previous VK_EXT_debug_report and VK_EXT_debug_marker extensions were
both deprecated in favor of VK_EXT_debug_utils. This commit makes Dawn
follow the ecosystem and also adds more detailed reporting of why
vkCreateInstance fails that's now supported in VK_EXT_debug_utils.

73b70229af dawn.json: Expose the driver version in the adapter.
And use it to print the driver version at the start of
dawn_end2end_tests. This will help when figuring out issues
happening on CQ but not necessarily locally.

eec9edfd57 Standardize the use of UNREACHABLE in switches.
A lot of our switches over enum values use the following pattern:

    default:
        UNREACHABLE();
        return foo;

This is problematic because when adding a new value to one of the WebGPU
enums, there is no compilation error for switches that are missing it.
Currently we're supposed to write code and tests and fix UNREACHABLEs when
we see them.

Instead we should strive to have most switches on enums to be complete
and explicitily tag unreachable values as UNREACHABLE. Some switches
might still want to use default: UNREACHABLE() if only a couple values
need to be handled out of very many.

In this CL we go through all the UNRAECHABLEs and change them if need
be. Also an ErrorQueue class is added to avoid having
QueueBase::SubmitImpl just be UNREACHABLE (and force overriding
instead).

5cef1162b9 Reland: Vulkan: Report and enable subgroup size control device extension.
Reland after a refactor of how the extension handling work in the Vulkan
backend.

The original author is David Turner <david.turner.dev@gmail.com>.

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:

- 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.

- This modifies VulkanDeviceInfo::GatherDeviceInfo() to
  use PNextChainBuilder to query extension features and properties
  in a single call to vkGetPhysicalDevice{Properties,Features}2.

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.

5c9f7af77d Vulkan: Properly handle Device extension dependencies
The checks for dependencies of Device extensions were incomplete, makes
sure the transitive dependencies of the extensions we care about are all
known so they can participate in the dependency check.

Also removes a workaround for surprising Vulkan behavior with instance
extensions getting promoted as device functions. This should be handled
correctly now as DeviceExt contains the physical device extensions as
well.

265fb062be Vulkan: handle Device extensions more programmatically
Similarly to the CL for Instance extensions, it makes each device
extension linked to an enum class and a bitset. Logic surrounding device
extensions is changed to take advantage of this to be more programmatic
and less error prone when adding support for a new extension.

0dc70785d8 Vulkan: handle Instance extensions more programmatically
At the moment each instance extension needs special handling
in 6+ places when added to the Vulkan backend. This is very
error-prone and makes it difficult to do changes in how they
are extensions are handled.

This CL makes instance extensions linked with an enum class
and a bitset to know which are available (instead of individual
booleans). A table of known extensions with more information like
`versionPromoted` so that they can be handled programmatically.
