Append interface link libraries into the bundle

Fixes an issue of undefined symbols from the monolithic
shared bundle library by appending dependencies found in the
`INTERFACE_LINK_LIBRARIES` in addition to `LINK_LIBRARIES`.
This is required since `LINK_LIBRARIES` does not contain the transitive
dependencies advertised by a target, due to which the bundle ended up
with undefined symbols.

Without this CL,

```
nm ./libwebgpu_c_bundled.so | grep " U " | grep -vE '(GCC|GLIBC|CXXABI)' && echo "not ok" || echo "ok"

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.
