[Opt](scanner-scheduler) Optimize BlockingQueue, BlockingPriorityQueue and change remote scan thread pool. ( #26784 )
...
## Proposed changes
- Optimize `BlockingQueue`, `BlockingPriorityQueue` by swapping `notify` and `unlock` to reduce lock competition. Ref: https://www.boost.org/doc/libs/1_54_0/boost/thread/sync_bounded_queue.hpp
- Change remote scan thread pool to `PriorityQueue`.
### Test result
Before:
```
mysql> select sum(lo_partkey) from lineorder;
+-----------------+
| sum(lo_partkey) |
+-----------------+
| 300021444265405 |
+-----------------+
1 row in set (1.11 sec)
```
After:
```
mysql> select sum(lo_partkey) from lineorder;
+-----------------+
| sum(lo_partkey) |
+-----------------+
| 300021444265405 |
+-----------------+
1 row in set (0.80 sec)
```
