Yanqin Jin 5237b39d2e Fix assertion error during compaction with write-prepared txn enabled (#9105)
Summary:
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9105

The user contract of SingleDelete is that: a SingleDelete can only be issued to
a key that exists and has NOT been updated. For example, application can insert
one key `key`, and uses a SingleDelete to delete it in the future. The `key`
cannot be updated or removed using Delete.
In reality, especially when write-prepared transaction is being used, things
can get tricky. For example, a prepared transaction already writes `key` to the
memtable after a successful Prepare(). Afterwards, should the transaction
rollback, it will insert a Delete into the memtable to cancel out the prior
Put. Consider the following sequence of operations.

```
// operation sequence 1
Begin txn
Put(key)
Prepare()
Flush()

Rollback txn
Flush()
```

There will be two SSTs resulting from above. One of the contains a PUT, while
the second one contains a Delete. It is also known that releasing a snapshot
can lead to an L0 containing only a SD for a particular key. Consider the
following operations following the above block.

```
// operation sequence 2
db->Put(key)
db->SingleDelete(key)
Flush()
```

The operation sequence 2 can result in an L0 with only the SD.

Should there be a snapshot for conflict checking created before operation
sequence 1, then an attempt to compact the db may hit the assertion failure
below, because ikey_.type is Delete (from a rollback).

```
else if (clear_and_output_next_key_) {
  assert(ikey_.type == kTypeValue || ikey_.type == kTypeBlobIndex);
}
```

To fix the assertion failure, we can skip the SingleDelete if we detect an
earlier Delete in the same snapshot interval.
