tint_cmd: Flush stderr after emitting non-error diagnostics

And before we emit the output program to stdout. This is important to
ensure that the output is emitted immediately rather than buffered,
especially since we write to both stdout and stderr. For example, we
emit diagnostics to stderr, but the wgsl program to stdout, and without
flushing, the ordering of this output is not guaranteed. We depend on
this ordering for our Tint e2e tests (comparing saved output to emitted
output), and on the Dawn LUCI bots, these tests failed because
diagnostic messages were emitted after the wgsl program.

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.
