Summary:
The patch builds on https://github.com/facebook/rocksdb/pull/9915 and adds
a new API called `PutEntity` that can be used to write a wide-column entity
to the database. The new API is added to both `DB` and `WriteBatch`. Note
that currently there is no way to retrieve these entities; more precisely, all
read APIs (`Get`, `MultiGet`, and iterator) return `NotSupported` when they
encounter a wide-column entity that is required to answer a query. Read-side
support (as well as other missing functionality like `Merge`, compaction filter,
and timestamp support) will be added in later PRs.

Summary:
This PR is the second and last part for adding user defined timestamp support to read only DB. Specifically, the change in this PR includes:
- `options.timestamp` respected by `CompactedDBImpl::Get` and `CompactedDBImpl::MultiGet` to return results visible up till that timestamp.
- `CompactedDBImpl::Get(...,std::string* timestsamp)` and `CompactedDBImpl::MultiGet(std::vector<std::string>* timestamps)` return the timestamp(s) associated with the key(s).
