partition_alloc: CMake and GN config

Start using "partition_alloc" in Dawn using both GN and CMake.
This is accompanied with a minimal usage to prove it works correctly.

This is a new attempt. I reverted the previous one:
https://dawn-review.googlesource.com/q/commit:c5f72f7a85aeeb21d7a9a12f28918970def41880

This patch makes the partition_alloc dependency optional. This make it
easier to embed dawn to work across every BUILD system and embedders
(skia, ...).

Next steps:
- Enable BackupRefPtr and DanglingPointerDetector in tests (GN only).
- Apply MiraclePtr rewrite.
- (stretch) clang-tidy enforcement

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.
