Migrate Value::Find*Path() calls in /google_apis

Value::Find*Path() is deprecated in favor of
Value::Dict::FindByDottedPath(), so swap out the former for the latter.
Also switch callsites that were using a hard-coded path without dots to
Value::Dict::Find() instead. Also, in some cases, migrate a couple other
nearby deprecated base::Value methods as well.
