Pre-handle SSTFiles to DTFiles when applying snapshots (pingcap#1439) (pingcap#1867)

* Add `raft.snapshot.method` in configuration file to control the method of applying snapshots
  - "block" decode snapshot data as a block
  - "file1" decode snapshot data as DTFiles (directory mode) [**By default**]
* Add a stream `SSTFilesToBlockInputStream` to decode snapshot data into blocks
* Add a stream `BoundedSSTFilesToBlockInputStream` to bound the blocks read from SSTFilesToBlockInputStream by column `_tidb_rowid`
* Add a stream `SSTFilesToDTFilesOutputStream` that accept `BoundedSSTFilesToBlockInputStream` as input stream to write blocks into DTFiles
* Make `STORAGE_FORMAT_CURRENT` to be `STORAGE_FORMAT_V2` by default to support ingest DTFile into DT engine
* Fix the bug that the block decoded from SSTFile is not sorted by primary key and version (pingcap#1888)
* Fix panic with feature compaction filter with DTFile
* Fix ingest write amplification after snapshot apply optimization (pingcap#1913)

Eliminate the table lock between reading,writing and DDL operators for TiFlash (pingcap#1736) (pingcap#1858)

* Eliminate the table lock between reading,writing and DDL operators for TiFlash (pingcap#1736)

1. Port the latest `RWLock` for `IStorage` from Clickhouse. "phase-fair rwlocks have been shown to provide more predictable timings compared to task-fair rwlocks for certain workloads (for relatively low share of writes, <25%). Brandenburg B, Anderson J, (2010)"
2. Refactor the lock model for `IStorage` to eliminate the lock between reading, writing, and DDL operations.
3. Acquire table lock by QueryID/threadName instead of function name
4. Tombstone the database after receiving a "drop" DDL from TiDB. Physically drop the databases / tables after gc safe point.
5. Remove some outdated tests under `tests/mutable-test/txn_schema` (all those tests are ported into `tests/delta-merge-test/raft/schema`)

* Mark FIXME for conflict codes
