Skip building mCacheKey when not needed

RenderPipeline[Vk]::mCacheKey contains all shader SPIR-V and all the
Vulkan creation struct data. This results in a large mCacheKey size with
graphite, it's observed to be in tens of kilobytes and it quickly adds
up to megabytes for all of the RenderPipeline objects that are kept
alive.

mCacheKey is only used for serializing VkPipelineCache objects into
BlobCache. This path isn't used with the monolithic pipeline cache so
it's all unnecessary memory usage. Only need to build the cache key if
Toggle::VulkanMonolithicPipelineCache isn't enabled.

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.
