Summary: The patch cleans up the code and improves the consistency checks around adding/deleting table files in `VersionBuilder`. Namely, it makes the checks stricter and improves them in the following ways: 1) A table file can now only be deleted from the LSM tree using the level it resides on. Earlier, there was some unnecessary wiggle room for trivially moved files (they could be deleted using a lower level number than the actual one). 2) A table file cannot be added to the tree if it is already present in the tree on any level (not just the target level). The earlier code only had an assertion (which is a no-op in release builds) that the newly added file is not already present on the target level. 3) The above consistency checks around state transitions are now mandatory, as opposed to the earlier `CheckConsistencyForDeletes`, which was a no-op in release mode unless `force_consistency_checks` was set to `true`. The rationale here is that assuming that the initial state is consistent, a valid transition leads to a next state that is also consistent; however, an *invalid* transition offers no such guarantee. Hence it makes sense to validate the transitions unconditionally, and save `force_consistency_checks` for the paranoid checks that re-validate the entire state. 4) The new checks build on the mechanism introduced in https://github.com/facebook/rocksdb/pull/6862, which enables us to efficiently look up the location (level and position within level) of files in a `Version` by file number. This makes the consistency checks much more efficient than the earlier `CheckConsistencyForDeletes`, which essentially performed a linear search.

Summary: The implementation of GetApproximateSizes was inconsistent in its treatment of the size of non-data blocks of SST files, sometimes including and sometimes now. This was at its worst with large portion of table file used by filters and querying a small range that crossed a table boundary: the size estimate would include large filter size. It's conceivable that someone might want only to know the size in terms of data blocks, but I believe that's unlikely enough to ignore for now. Similarly, there's no evidence the internal function AppoximateOffsetOf is used for anything other than a one-sided ApproximateSize, so I intend to refactor to remove redundancy in a follow-up commit. So to fix this, GetApproximateSizes (and implementation details ApproximateSize and ApproximateOffsetOf) now consistently include in their returned sizes a portion of table file metadata (incl filters and indexes) based on the size portion of the data blocks in range. In other words, if a key range covers data blocks that are X% by size of all the table's data blocks, returned approximate size is X% of the total file size. It would technically be more accurate to attribute metadata based on number of keys, but that's not computationally efficient with data available and rarely a meaningful difference. Also includes miscellaneous comment improvements / clarifications. Also included is a new approximatesizerandom benchmark for db_bench. No significant performance difference seen with this change, whether ~700 ops/sec with cache_index_and_filter_blocks and small cache or ~150k ops/sec without cache_index_and_filter_blocks.

Summary: `IterKey::UpdateInternalKey()` is an error-prone API as it's incompatible with `IterKey::TrimAppend()`, which is used for decoding delta-encoded internal keys. This PR stops using it in `BlockIter`. Instead, it assigns global seqno in a separate `IterKey`'s buffer when needed. The logic for safely getting a Slice with global seqno properly assigned is encapsulated in `GlobalSeqnoAppliedKey`. `BinarySeek()` is also migrated to use this API (previously it ignored global seqno entirely).

Summary: Preliminary user-timestamp support for delete. If ["a", ts=100] exists, you can delete it by calling `DB::Delete(write_options, key)` in which `write_options.timestamp` points to a `ts` higher than 100. Implementation A new ValueType, i.e. `kTypeDeletionWithTimestamp` is added for deletion marker with timestamp. The reason for a separate `kTypeDeletionWithTimestamp`: RocksDB may drop tombstones (keys with kTypeDeletion) when compacting them to the bottom level. This is OK and useful if timestamp is disabled. When timestamp is enabled, should we still reuse `kTypeDeletion`, we may drop the tombstone with a more recent timestamp, causing deleted keys to re-appear.
