Vulkan: Track and set dynamic state

If the vulkan_use_extended_dynamic_state toggle is enabled, tracks
several render pipeline properties and sets them dynamically when
the pipeline is bound. Specifically tracks the following states:

 - Primitive Topology
 - Cull Mode
 - Front Face
 - Depth Test Enabled
 - Depth Write Enabled
 - Depth Compare Op
 - Stencil Test Enabled
 - Stencil Op

Does make some effort to ensure that the Vulkan blob cache can be
hit more often when dynamic state is used, but more could be done
to improve caching.

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.
