Implement monolithic VkPipelineCache toggle

Dawn/Vulkan was using a VkPipelineCache per unique pipeline previously.
This hurts pipeline/shader compilation performance since many pipelines
produce the same binary blobs. Add a VulkanMonolithicPipelineCache
toggle that switches to using a single VkPipelineCache per wgpu::Device.

The existing behaviour to serialize VkPipelineCache into BlobCache
immediately after pipeline compilation is more problematic with a single
VkPipelineCache since it can get quite large. With monolithic cache it
will just mark that serialization is needed. PerformIdleWork() is added
to dawn native device to trigger this serialization at a time of the
embedders choosing, preferably when it's not going to hinder
performance.

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.
