d28b578b6b Disallow storage buffer binding in vertex shader
Writable storage buffer in vertex shader is an optional feature.
It is not supported in many devices/OSes. WebGPU doesn't support
writable storage buffer in vertex shader. This change generates an
error for storage buffer binding for vertex shader stage, in order
to disallow writable storage buffer in vertex shader.

This change also adds a validation test and revises existing
end2end tests and validation tests accordingly.

1586b4d73e Vulkan: prevent degenerate buffer sizes from reaching the driver
Allocating buffers with sizes close to UINT64_MAX caused issues in all
Vulkan drivers. See https://gitlab.khronos.org/vulkan/vulkan/issues/1904
for more context. Do early validation to prevent such cases from

6ea362cae0 fuzzing: Add error injection macros to the Vulkan backend
This will enable fuzzing the Vulkan backend with randomly injected
errors to help ensure the backend properly handles all errors. It also

2c8a17ecc7 Refactor Device destructors to WaitForIdleForDestruction + Destroy
To help with Device Loss, this splits Device backend destructors
to WaitForIdleForDestruction and Destroy.

WaitForIdleForDestruction waits for GPU to finish, checks errors and gets
ready for destruction.

Destroy is used to clean up and release resources used by device,
does not wait for GPU or check errors.

be5c135672 Refactor code to have rudimentary support for using SPVC
This is the first step for having a fully operational SPVC usage
path. This version of SPVC integration uses SPVC for setting up the
options to the compiler, but a lot of the actual interaction with
spirv-cross is done in Dawn, just via SPVC's compiler object.

Future CLs will migrate more of the spirv-cross interaction to using
the SPVC API, eventually removing the need for Dawn to know about
spirv-cross.

d0993ba83a Test TextureComponentType and TextureViewDimension compatibility
The TextureComponentType and TextureViewDimension of resources in
the shader must match those in the bind group layout.

This patch also extracts the texture view dimension from the SPIRV.

4b0b7a532a Skip validation during command recording when skip_validation is on
This patch factors resource usage tracking so it is separate from
command validation, allowing the bulk of command validation to be
completely skipped.

In DrawCallPerfRun/Vulkan_DynamicPipeline_DynamicBindGroup, disabling
validation cuts roughly 74 nanoseconds (20%) of CPU time, per draw.

In DrawCallPerfRun/Vulkan_DynamicBindGroup, disabling validation
cuts roughly 35 nanoseconds (17%) of CPU time, per draw.

In DrawCallPerfRun/Vulkan_MultipleBindGroups, disabling validation
cuts roughly 45 nanoseconds (14%) of CPU time, per draw.

48bf745b96 Revert "Convert spvc build flag to a runtime toggle"
This reverts commit 1954436fe28557dab8381f5b0f8ca7d68ab091c8.

Reason for revert:
The shaderc side of this multi-patch brings in a dependency on glslang, which uses a static initializer, which chromium doesn't like.

Original change's description:
> Convert spvc build flag to a runtime toggle
> 
> Also moves some of the spirv_cross code into the main library that was
> feature guarded, since spvc requires it.

12e780d709 Fix D3D12 render-pass failure when GPU does not support sampling positions.
It is invalid to specify a resolve source region on GPUs that do not
support sample positions. Instead, the entire region rect should be
set to all zeros or "empty" to always resolve the entire region.

899c17090f Implement a dma-buf MemoryService
This CL implements the MemoryService for importing memory and
creating VkImages from a dma-buf handle. Under the hood, it uses the
VK_EXT_external_memory_dma_buf and
VK_EXT_image_drm_format_modifier extensions to find a memory type
that supports dma-buf import. In addition, the extensions are also
used to properly specify the stride and tiling of the dma-buf to
vkAllocateMemory and vkCreateImage.

98ba76af00 Define an interface to import dma-bufs
This CL adds an API to import a dma-buf into Dawn as a WGPUTexture.

We also add a descriptor type enum to the base
ExternalImageDescriptor struct. This is because all memory import
code (e.g. MemoryService, Texture::CreateFromExternal) takes the
a base ExternalImageDescriptor as a parameter. The dma-buf external
memory and image services, however, will need to downcast to
ExternalImageDescriptorDmaBuf to access import parameters like
stride. Explicitly adding a type enum will let us more safely verify
the type before downcasting.

ae687f5b83 Add CreateImage support to MemoryService
This CL introduces SupportsCreateImage and CreateImage to the
external memory service API to provide different implementations for
creating VkImages for different types of external image handles.

While opaque FD and Zircon seem to share the same vkCreateImage
implementation, dma-buf import will require the use of the
VkImageDrmFormatModifierExplicitCreateInfoEXT [1] struct (among
other differences) with vkCreateImage.

756a9d7e49 Create VkImage before importing external memory
This CL is part of a chain of CLs that imports dma-bufs as VkImages
to support WebGPU on Chrome OS.

There are currently two steps for importing external memory into
Vulkan:

  1. DeviceVk::ImportExternalImage: calls into
     MemoryServiceOpaqueFD::ImportMemory which in turn calls into
     vkAllocateMemory and outputs a VkDeviceMemory handle to the
     imported memory.
  2. TextureVk::CreateFromExternal: creates the actual TextureVk
     object, creates the VkImage, and binds the VkDeviceMemory from
     ImportExternalImage to the VkImage.

For dma-buf support, however, we need to re-order these two steps
because importing dma-buf memory requires a handle to the VkImage
that will alias it [1].

This CL splits these two steps into three steps to ensure we create
the VkImage first so we can use it in vkAllocateMemory:

  1. TextureVk::CreateFromExternal: creates the TextureVk and
     VkImage (no longer concerns itself with vkBindImageMemory).
  2. DeviceVk::ImportExternalImage: now takes the VkImage as input
     but is otherwise unchanged.
  3. TextureVk::BindExternalMemory: calls vkBindImageMemory with
     handles to VkDeviceMemory and VkImage.

083a1ce2bf Inline a 1 bit payload in RefCounted
This changes RefCounted to increment and decrement the refcount by steps
of 2, so that a 1 bit payload can be inlined in the refcount. This
avoids using a whole boolean + padding (4 or 8 bytes in general) to know
if objects are errors.

Fixes a longstanding optimization TODO.
