Miroslav Kovar fc2cf7ead2 Expose optimized TransactionBaseImpl::MultiGet through JNI (#13589) 
Summary:
Addresses https://github.com/facebook/rocksdb/issues/13587.

This PR exposes the optimized implementation of batched reads through a `Transaction` object to Java clients.

The latency improvement of transactional multiget on production workload achieved by switching the implementation is roughly:
```
quantile=0.2: 21%
quantile=0.5: 28%
quantile=0.8: 46%
quantile=1.0: 239%
```
