Islam AbdelRahman f38540b12a WriteBatchWithIndex micro optimization
Summary:
  - Put key offset and key size in WriteBatchIndexEntry
  - Use vector for comparators in WriteBatchEntryComparator

I use a slightly modified version of @yoshinorim code to benchmark
https://gist.github.com/IslamAbdelRahman/b120f4fba8d6ff7d58d2

For Put I create a transaction that put a 1000000 keys and measure the time spent without commit.
For GetForUpdate I read the keys that I added in the Put transaction.

Original time:

```
 rm -rf /dev/shm/rocksdb-example/
 ./txn_bench put 1000000
 1000000 OK Ops | took      3.679 seconds
 ./txn_bench get_for_update 1000000
 1000000 OK Ops | took      3.940 seconds
```

New Time

```
  rm -rf /dev/shm/rocksdb-example/
 ./txn_bench put 1000000
 1000000 OK Ops | took      2.727 seconds
 ./txn_bench get_for_update 1000000
 1000000 OK Ops | took      3.880 seconds
```

It looks like there is no significant improvement in GetForUpdate() but we can see ~30% improvement in Put()
