Jiawei Shao 63f2666ee7 Check bind group layout with storage texture in pipeline descriptors
This patch adds all the validations on the use of bind group layout with
read-only storage texture and write-only storage texture in the creation
of pipeline objects.

1. GPUBindGroupLayout.bindingType must match the type of the storage
   texture variable (read-only or write-only) in shader.
2. GPUBindGroupLayout.storageTextureFormat must be a valid texture
   format that supports STORAGE usage.
3. GPUBindGroupLayout.storageTextureFormat must match the storage
   texture format declaration in shader.
4. GPUBindGroupLayout.textureDimension must match the storage texture
   dimension declared in shader.

Ryan Harrison b988e03982 Add in a default case to unblock shaderc rolls
The roll in Chromium is failing, because Dawn doesn't handle all of the new enum
values, but I cannot land the 'proper' fix in Dawn, because Chromium doesn't yet
know about the new enum values. Yay, cross dependencies.

So my solution is land the default case in Dawn, land the DEPS roll in Chromium,
then patch in the 'proper' cases in Dawn.

This patch adds the basic validation of read-only storage texture,
write-only storage texture and read-write storage texture as new
binding types with no bind group layout provided in the creation of
pipeline state objects.

- Read-only storage textures can be used in vertex, fragment and
  compute shaders.
- Write-only storage textures can only be used in compute shaders
  due to the limitation on Metal.
- Read-write storage textures are not allowed now and they are
  reserved to be supported as an extension in the future.

Jiawei Shao 532be50b76 Check bindingType with shader stage when creating default pipeline layout
This patch intends to fix a crash issue when creating a rendering
pipeline with storage buffer declared in vertex shader and pipeline
layout is not set.

Without this patch, in PipelineLayoutBase::CreateDefault() the
bindingSlot.visibility is always set to Fragment and Compute when it is
a storage buffer, therefore a crash happens at the failure of the
assertion modules->IsCompatibleWithPipelineLayout() when the storage
buffer is actually declared in the vertex shader.

David Turner 56f1678437 Vulkan: Enforce fixed subgroup size for compute shaders.
This CL ensures that, on architectures with a varying subgroup size,
compute shaders are always compiled with a fixed subgroup size to
avoid consistency issues when one shader writes data in a subgroup-size
dependent layout to GPU memory, to be read by another shader in a
future dispatch.

At the moment, only Intel ICDs are known to implement this [1],
and the code uses a heuristics to chose the size of 16, which seems to
be the sweet spot according to Intel engineers.

+ Update the PNextChainBuilder class to deal with the fact that
  VkComputePipelineCreateInfo::pNext is defined as a const void*,
  which created compiler errors in the previous implementation.

David Turner 4ae315b0d1 Vulkan: Report and enable subgroup size control device extension.
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.
