Make TracedDictionary/Array implicitly constructible from TracedValue.
Allow TracedDictionary & TracedArray to be implicitly constructed from
TracedValue, similarly to TracedProto<T>.
This will allow to simplify a common case of writing a nested dictionary
/ array from
TRACE_EVENT("cat", "E", "data", [](perfetto::TracedValue ctx) {
perfetto::TracedDictionary dict = std::move(ctx).WriteDictionary();
dict.Add(...);
});
to
TRACE_EVENT("cat", "E", "data", [](perfetto::TracedDictionary dict) {
dict.Add(...);
});
