Add object type (#1948)

Browse Source 
Add a new type: Object. Currently, it's mainly for complex aggregate metrics(HLL , Bitmap).

The Object type has the following constraints：
1 Object type could not as key column type
2 Object type doesn't support all indices (BloomFilter, short key, zone map, invert index)
3 Object type doesn't support filter and group by

In the implementation：

The Object type reuse the StringValue and StringVal, because in storage engine, the Object type is binary, it has a pointer and length.
