GL: Add ExecuteGL() method for unordered GL commands

Some GL commands, like resource creation, don't depend on prior
commands in the queue. Flushing the entire pending command list for
them is unnecessary.

This change introduces `Device::ExecuteGL` to execute a
command immediately without a preceding flush. The existing work
execution function is renamed to `EnqueueAndFlushGL` to clarify its
flushing behavior.

This allows for more efficient execution of independent GL tasks.

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.
