The first atomic increments of ref counts are generally unneeded if the ref count starts from 1 instead of 0, and we can detect an invalid AddRef from 0 to 1 in that case. Especially, the ref count in BindStateBase is incremented 300k times in its constructor by the first page load from the browser boot, and also it sometimes hits invalid state. Note that 300k atomic increments are probably not so time consuming as we can measure. This CL adds `base::AdoptRef` to scoped_refptr for ref counted types whose ref count start from 1, and converts BindStateBase to use it.
