[toggles] Set labels on backend objects only if toggle is set

We have found that in Chrome, setting these labels can be a source of
non-trivial overhead on performance benchmarks. This CL guards setting
of these labels with the `use_user_defined_labels_in_backend` toggle.
Note that labels will still be set on frontend objects, and hence will
still be available in e.g. Dawn error messages. The labels on the
backend objects are relevant only when debugging via platform-specific
facilities (e.g., XCode).

This CL also changes the `use_user_defined_labels_in_backend` toggle to
default to true on Vulkan. These labels are necessary on Vulkan to map
errors back to the devices with which objects generating the errors
are associated. See a detailed description here [1].

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.
