1. Adds BaggagePropagation benchmarks for decorate …

   I tried a couple ways to optimize ExtraFactory with regards to supplying
   the extraList directly, including some special casing of singleton list
   and using `InternalPropagation.instance.withExtra(context,
   unmodifiableList(newExtra));` on a pre-sized list. The results of
   routine case always ended up with more allocation than now.
   
   This adds a benchmark, so people don't think like I did and feel there
   is a quick change that won't hurt others. It is possible that the bench
   isn't representative, or more angles need to be looked at, but this
   should help people understand where to start.
   
   ```
