Fix linker errors for android webgpu library

- The android build failed because `webgpu_dawn` was changed into a shared
  library in https://dawn-review.googlesource.com/c/dawn/+/194920. As a
  result, `bundle_libraries` failed to enumerate it's objects and
  dependencies correctly.

- In order to avoid having two bundled libraries for android, the `webgpu_dawn`
  library is no longer built in favor of the `webgpu_c_bundled` library which
  gets built in tools/android/webgpu/src/main/cpp/CMakeLists.txt.

- This CL adapts the logic for the android library in light of recent
  updates to the CMake code.

- The intermediate `native_dawn` library is removed and it's sources
  along with `webgpu_dawn_native_proc.cpp` are directly sent to the
  `webgpu_c_bundled` library.

- Finally, `webgpu_c_bundled` links with `dawn_public_config` in order
  to inherit the public include directories for `dawn/webgpu.h`.

- Since `webgpu_dawn` is no longer built for android, this CL changes
  the custom copy command to depend upon `dawncpp_headers` which
  generates the `dawn/webgpu.h` header.

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.
