This CL moves native assets resolution to the embedder. The Dart VM looks up the asset path (for example `['relative', 'foo.so']`) with the asset id. The embedder defines callbacks for asset loading, and returns a handle to the dylib. Then the VM calls the embedder again with `dlsym` to lookup the symbol. The Dart VM & kernel compiler are responsible for the asset id to asset path mapping. The kernel compiler compiles it into the snapshot and the VM looks it up in the snapshot. Relative paths are resolved relative to the isolate script uri (kernel snapshot, jit snapshot, aot snapshot, or `dart compile exe` result). The embedder is responsible for remembering the script uri it set when spawning the isolate group. This CL does not add `dlclose` or `dladdr` embedder callbacks yet.
