Summary:
BYTES_WRITTEN accounting doesn't work with disabled WAL. For example, this is what we
get in the LOG:
```
Cumulative writes: 9794K writes, 228M keys, 9794K commit groups, 1.0
writes per commit group, ingest: 0.00 GB, 0.00 MB/s
```
WAL bytes are tracked in a different statistic:
https://github.com/facebook/rocksdb/blob/master/db/internal_stats.h#L105.
BYTES_WRITTEN should count all the writes.

Summary:
1. Move universal compaction picker to separate files compaction_picker_universal.cc and compaction_picker_universal.h.
2. Rename some functions to make the code easier to understand.
3. Move leveled compaction picking code to a dedicated class, so that we we don't need to pass some common variable around when calling functions. It also allowed us to break down LevelCompactionPicker::PickCompaction() to smaller functions.
