[SPARK-22524] Subquery shows reused on UI SQL tab even if it's not reused
After manually disabling `reuseSubquery` rule, the subqueries won't be
reused. But on the SQL graph, there is only one subquery node and it looks like
subquery is reused.
`SparkPlanGraph` compares different `SparkPlanInfo`s by comparing their
`simpleString`, which requires us to design `simpleString` well. While
`SubqueryExec`'s `simpleString` depends only on the `exprId`, so we need to add
extra index to its name.
