remove json functions code
remove string functions code
remove math functions code
move MatchPredicate to olap since it is only used in storage predicate process
remove some code in tuple, Tuple structure should be removed in the future.
remove many code in collection value structure, they are useless
This PR optimize topn query like `SELECT * FROM tableX ORDER BY columnA ASC/DESC LIMIT N`.
TopN is is compose of SortNode and ScanNode, when user table is wide like 100+ columns the order by clause is just a few columns.But ScanNode need to scan all data from storage engine even if the limit is very small.This may lead to lots of read amplification.So In this PR I devide TopN query into two phase:
1. The first phase we just need to read `columnA`'s data from storage engine along with an extra RowId column called `__DORIS_ROWID_COL__`.The other columns are pruned from ScanNode.
2. The second phase I put it in the ExchangeNode beacuase it's the central node for topn nodes in the cluster.The ExchangeNode will spawn a RPC to other nodes using the RowIds(sorted and limited from SortNode) read from the first phase and read row by row from storage engine.
After the second phase read, Block will contain all the data needed for the query

1.Support in bitmap syntax, like 'where k1 in (select bitmap_column from tbl)';
2.Support bitmap runtime filter. Generate a bitmap filter using the right table bitmap and push it down to the left table storage layer for filtering.
This PR is to make sharing hash table for broadcast more robust:
Add a session variable to enable/disable this function.
Do not block the hash join node's close function.
Use shared pointer to share hash table and runtime filter in broadcast join nodes.
The Hash join node that doesn't need to build the hash table will close the right child without reading any data(the child will close the corresponding sender).
#13195 left some unresolved issues. One of them is that some BE unit tests fail.
This PR fixes this issue. Now, we can run the command ./run-be-ut.sh --run successfully on macOS.
For runtime filter, signal will be called by a thread which is different from the await thread. So there will be a potential race for variable is_ready
to_bitmap function only support string param only，add to_bitmap() function with int type, this can avoid convert int type to string and then convert string to int
