spawn_buffered will be dead-locked under current-thread tokio runtime #7206
Description
Describe the bug
spawn_buffered function will use tokio context to spawn the execution of stream if tokio runtime is started. However, if the started runtime is current-thread and it is blocked on, spawned tasks could be possibly dead-locked.
To Reproduce
Constructs a tokio current-thread runtime and uses it to block on a physical query execution which has used spawn_buffered function, e.g., Sort.
