[BEAM-2333] Use RehydratedComponents for memoized rehydration
Follow this checklist to help us incorporate your contribution quickly and
easily:
- [x] Make sure there is a [JIRA
issue](https://issues.apache.org/jira/projects/BEAM/issues/) filed for the
change (usually before you start working on it). Trivial changes like typos do
not require a JIRA issue. Your pull request should address just this issue,
without pulling in other changes.
- [x] Each commit in the pull request should have a meaningful subject
line and body.
- [x] Format the pull request title like `[BEAM-XXX] Fixes bug in
ApproximateQuantiles`, where you replace `BEAM-XXX` with the appropriate JIRA
issue.
- [x] Write a pull request description that is detailed enough to
understand what the pull request does, how, and why.
- [x] Run `mvn clean verify` to make sure basic checks pass. A more
thorough check will be performed on your pull request automatically.
- [x] If this contribution is large, please file an Apache [Individual

This add a `RehydratedComponents` which memoizes every rehydrated Coder,
PCollection, and WindowingStrategy. For PCollections this is mandatory so they
can be wired up correctly, while for Coder and WindowingStrategy it is nice to
have to limit the number of extra objects we create - though the total count is
tiny no matter what, it aids debugging and testing to have fewer.
