This reverts commit 0bbfec1f7f5e0dd92c17e2f8055d16a41fef7558.
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

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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- 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
