Fix leak of the eager exportable VkSemaphore.

Exporting an exportable VkSemaphore doesn't implicitly destroy the
VkSemaphore object. So instead of Detach()ing the VkSemaphore when it is
first consumed, just let it go out of the scope and be destroyed with
RAII. This also fixes the RAII by not destroying the VkSemaphore
immediately and instead wait until it becomes unused.

Found by running dawn_end2end_tests with the VVLs.

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.
