Yanqin Jin 7d26e4c5a3 Basic Support for Merge with user-defined timestamp (#10819) 
Summary:
This PR implements the originally disabled `Merge()` APIs when user-defined timestamp is enabled.

Simplest usage:
```cpp
// assume string append merge op is used with '.' as delimiter.
// ts1 < ts2
db->Put(WriteOptions(), "key", ts1, "v0");
db->Merge(WriteOptions(), "key", ts2, "1");
ReadOptions ro;
ro.timestamp = &ts2;
db->Get(ro, "key", &value);
ASSERT_EQ("v0.1", value);
```

Some code comments are added for clarity.

Note: support for timestamp in `DB::GetMergeOperands()` will be done in a follow-up PR.
