Expose WriteBatchWithIndex in c.h

• https://rocksdb.org/blog/2015/02/27/write-batch-with-index.html
• Is WriteBatchWithIndex supported? rust-rocksdb/rust-rocksdb#836

Perhaps we can export this class to c.h as it's export to JNI already, so that other language bindings can make use of it.

rocksdb/include/rocksdb/utilities/write_batch_with_index.h

Line 86 in f6fd4b9

class WriteBatchWithIndex : public WriteBatchBase {

rocksdb/java/src/main/java/org/rocksdb/WriteBatchWithIndex.java

Line 22 in f6fd4b9

public class WriteBatchWithIndex extends AbstractWriteBatch {

Sorry, it's already exposed as rocksdb_writebatch_wi_t.
