Re-enable compilation of GL backends in Chromium.

Tint's GLSL backend has achieved test parity with the SPIRV-Cross path
for dawn_end2end_tests on both Desktop and ES and we have switched
exclusively to Tint for GLSL generation. Since the SPIRV-Cross
dependency has been removed, there should no longer be any binary size
concerns with the use of these backends in Chrome.

This reverts commit 6ef39372f8b6d60d927a5e6ae4eb27389f24eced.

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 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
