Corentin Wallez 21e5074dcd Revert "Create VulkanImageWrappingTests for dma-buf images"
This reverts commit 0bbfec1f7f.

Reason for revert: Makes the roll into Chromium fail with the following:

    [314/21578] CXX obj/third_party/dawn/dawn_white_box_tests_sources/VulkanImageWrappingTestsDmaBuf.o
    FAILED: obj/third_party/dawn/dawn_white_box_tests_sources/VulkanImageWrappingTestsDmaBuf.o
    ../../build/toolchain/clang_code_coverage_wrapper.py --target-os=chromeos --files-to-instrument=../....(too long)
    ../../third_party/dawn/src/tests/white_box/VulkanImageWrappingTestsDmaBuf.cpp:28:10: fatal error: 'drm/drm_fourcc.h' file not found
    #include <drm/drm_fourcc.h>

Original change's description:
> Create VulkanImageWrappingTests for dma-buf images
> 
> This CL branches the existing VulkanImageWrappingTests to separate
> tests for OpaqueFD-backed amd DmaBuf-backed external images. On
> Chrome OS of Dawn, we no longer interop using opaque FDs, so these
> tests were failing in the end2end test suite.
> 
> The new VulkanImageWrappingTestsDmaBuf tests are essentially 1:1
> mappings of their counterparts in the Opaque FD version. The only
> difference is that we allocate memory directly on the device using
> GBM instead of creating a VkImage (which will likely call some GBM
> methods under the hood) and then extracting the FD using a Vulkan
> extension. We then communicate this to Dawn via the DmaBuf
> ExternalImageDescriptor.
> 
> Also, this fixes VulkanImageWrappingUsageTests::LargeImage on AMD
> devices (assuming the extension is implemented) as we can now
> specify DRM modifiers.
>

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A "native" implementation of WebGPU using platforms' GPU APIs:
    • D3D12 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
