Corentin Wallez 324e446f9c Vulkan: Add support for using dedicated allocation when importing images.
This is required to make importing images work on some systems. The
ideal version would be detecting whether dedicated allocations are
needed as Vulkan provides reflection for that. However this reflection
doesn't work on Nvidia, so instead Dawn requires a
NeedsDedicatedAllocation enum on import that's Yes/No/Detect so the
application can force use of a specific code path.

Support for this enum and toggling dedicated allocations on/off is added
for all external memory service implementations.

Vulkan image wrapping tests are modified to add test parameters so that
the Yes/No/Detect code paths are covered by tests.

This is technically post-V1 work, but gl_tests in Chromium fail on
Nvidia workstations without this fix, which makes it hard to debug other
issues.

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, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
