ElvinWei 436ee0dd1d [feature-wip](statistics) step4.1: manually inject statistics for a table or column (#11030 )

This pr mainly to supplement the syntax of the previous pr(#8861),
it supports users to manually inject statistics, including table, partition, and column statistics. 

table/partition stats type:
- row_count
- data_size

column stats type:
- ndv
- avg_size
- max_size
- num_nulls
- min_value
- max_value

Modify table or partition statistics:
```
ALTER TABLE table_name 
SET STATS ('k1' = 'v1', ...) [PARTITIONS(p_name1, p_name2...)]
```

Modify column statistics:
```
ALTER TABLE table_name MODIFY COLUMN columnName 
SET STATS ('k1' = 'v1', ...) [PARTITIONS(p_name1, p_name2...)]
```

Some notes:
- Only support statistics injected into olap type tables.
- Statistics injected into temporary partitions are not supported.
- When injecting statistics, if it is a partitioned table, users need to specify a partition name.
- If multiple partitions are specified, the same stats will be injected on multiple partitions.
- The current code also has mock statistics @zhengshij
