LiBinfeng 1e54a5a66e [Fix](Nereids) fix leading with brace can not generate correct plan (#36328)
cherry-pick #36193

Problem:
when using leading like:
leading(t1 {t2 t3} {t4 t5} t6)
it would not generate correct plan because levellist can not express
enough message of braces
Solved:
remove levellist express of leading levels and use reverse polish
expression
Algorithm:
leading(t1 {t2 t3} {t4 t5} t6)
==>
stack top to down(t1 t2 t3 join join t4 t5 join t6 join) when generate
leading join, we can pop items in stack, when it's a table, make
logicalscan when it's a join
operator, make logical join and push back to stack
